The COVID-19 pandemic, continues to impact many people, including cancer patients, their families, and caregivers.Vaccines help a person’s immune system to recognize and protect the body against infections. COVID-19 vaccines have been found to significantly lower the risk of getting infected with COVID-19, lower the risk of having severe disease, being hospitalized, or dying from COVID-19 if one gets infected. 

Here we’ll discuss some frequently asked questions by people with cancer or a history of previous cancer have about the COVID-19 vaccines.

1) Should cancer patients and survivors take the COVID-19 vaccine?

Patients with cancer or a history of cancer should get the COVID -19 vaccine whenever available. Many expert medical groups recommend patients with a recent cancer diagnosis and those on treatment should be given the highest priority. This is because cancer and its treatment can weaken the immune system putting such patients at risk for severe COVID-19 disease. Caregivers and household members of cancer patients should also be immunized whenever possible.

2) Is it safe for cancer patients to receive the COVID-19 vaccine?

At present, there is a lack of data regarding the safety and efficacy of COVID-19 vaccination in cancer patients. Numerous studies have shown that cancer patients are at higher risk for more severe COVID-19 disease and complications. There are no reports of increased risk for side effects of the vaccine in cancer patients. The risks of COVID-19 for cancer patients outweigh the very low risk of vaccination. Because of these, oncology groups including the American Society of Clinical Oncology (ASCO), the American Society of Hematology (ASH), and the American Society for Radiation Oncology have all recommended patients with cancer get vaccinated.

3) Is there any specific approved COVID-19 vaccine for cancer patients?

At this time, no major medical organizations have recommended getting one type of COVID vaccine over another, either for cancer patients or for other people. Health experts believe that getting the vaccine once it becomes available, whichever one it is, is most important, rather than waiting to get a specific vaccine. 

4) What are the side effects of the vaccines?

Common side effects that have been reported after getting the vaccines to include:
• Pain, redness, or swelling at the injection site
• Feeling tired
• Headache
• Fever
• Chills
• Muscle and joint pain
• Nausea

The incidence or the nature of side effects in cancer patients and survivors had been reported to be similar to with the general population. 

Some people (16%) might develop swelling or pain under the vaccinated arm. This is often a normal response by the body’s immune system to the vaccine. A swollen lymph node under the arm might cause concern since this can also be a sign of breast cancer spread.

Oncologists recommend that patients with breast cancer or a history of breast cancer get the vaccine in the arm on the unaffected side.

5) Are there any exceptions for COVID-19 vaccination among cancer patients?

There are few exceptions:

a) Vaccination should be delayed for at least 3 months following bone marrow transplantation and engineered cellular therapy to maximize vaccine efficacy.

b) Vaccination in patients undergoing intensive chemotherapy should be delayed until neutrophil count recovery.

c) Patients undergoing major surgery for cancer should have a gap of few days in-between.

In patients undergoing chemotherapy, the optimum timing for vaccination about the chemotherapy cycle is still unclear. The difference in the efficacy of the COVID-19 vaccine in terms of its immunogenic potential i.e. ability to generate antibodies against coronavirus- SARS-COV-2, when administered along with chemotherapy versus mid-cycle, is still unknown. In absence of robust data, the National Comprehensive Cancer Network (NCCN) for now recommends vaccination when available.

6) Will vaccination affect my cancer-related tests and scans?

Getting a COVID-19 vaccine might result in swollen lymph nodes under the arm in which the injection was given. Swollen lymph nodes might show up on a CT Scan or mammogram is done for breast cancer or other cancers, causing concern and confusion. It is important to communicate with your doctor if you are scheduled to get an imaging test (such as an MRI or CT scan) in the weeks after getting a COVID vaccine. 

7) Do I still need to take precautions if I get the COVID-19 vaccine?

While the vaccine can lower the risk of getting a serious disease from COVID, it doesn’t completely rule out the possibility of getting infected by the virus. It is also not yet clear how well vaccines can prevent the spread of the virus to others. Here it will be appropriate to mention that data tracking the immune response in patients with cancer who have been vaccinated are still evolving. Therefore, even after vaccination, it is advised that everyone continue to follow all COVID-19 prevention protocols.

An Indian Air Force (IAF) Tejas fighter jet crashed on Friday, November 21, afternoon during its aerial demonstration at the Dubai Air Show, plunging to the ground at around 2:10 pm local time while performing a manoeuvre before thousands of spectators.

The IAF confirmed the incident, stating that a Tejas aircraft participating in the show had crashed and that further details were being gathered. An Air Force spokesperson said more information would be shared after initial assessments.

The crash sent thick black smoke billowing into the sky near the airport, causing panic among visitors, including families and children who had gathered to watch the display. Authorities have not yet confirmed whether the pilot managed to eject before the aircraft went down. Emergency response teams rushed to the scene, and officials have not released information on casualties or damage so far.

The Tejas is a 4.5-generation, multi-role fighter aircraft developed indigenously by Hindustan Aeronautics Limited (HAL). Designed for versatility, it is capable of offensive air support, close combat, ground attack missions and maritime operations. The aircraft family includes single-seat fighters and twin-seat trainers for both the Air Force and Navy.

HAL describes the latest version, the LCA Mk1A, as the most advanced in the series, featuring an AESA radar, an upgraded electronic warfare suite with radar-warning and self-protection jamming, smart multifunction displays, a digital map generator, a combined interrogator–transponder system and a modern radio altimeter. These enhancements significantly improve the aircraft’s combat capability and survivability.

Further updates from IAF and UAE authorities are awaited.

Mangaluru, Nov 24: The original departure time of 11.10 pm was a distant memory for scores of Dammam-bound passengers at Mangaluru International Airport last Friday night, as their Air India Express flight was abruptly cancelled at the eleventh hour, sparking hours of frustration and chaos.

The flight, IX 885, initially scheduled to depart at 11.10 pm on November 22, was subject to two back-to-back reschedules—first pushed to 11.45 pm and then significantly postponed to 1.40 am—before the final, crushing announcement of cancellation was made. For the travellers, many of whom are likely expatriate workers with tight schedules, the last-minute change marked the beginning of a distressing ordeal.

"There was no drinking water, no food, and absolutely no proper guidance. We were left stranded like refugees," complained a stranded passenger.

According to multiple passenger accounts, the airline's ground staff failed to provide adequate support or essential amenities following the cancellation. Complaints poured in about the total absence of drinking water, food provisions, and any reliable guidance from the carrier's representatives. Travellers alleged they were left stranded for a considerable period, with no immediate arrangements or clear communication offered regarding accommodation or alternative travel to send them back home.

The incident has highlighted serious concerns over the carrier's contingency planning and customer service protocols during flight disruptions at one of India's key international gateways. The airline is yet to issue a comprehensive statement addressing the alleged lapse in passenger care.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.
