Currently, a number of other vaccines are awaiting approval. These include Covovax, developed by Novavax and the Coalition for Epidemic Preparedness Innovations; ZyCoV-D, developed by Cadila Healthcare; and BBV154 which is also being developed by Bharat Biotech.
Even though getting the Covid-19 vaccination is not mandatory in India, it can protect you against a deadly and virulent disease. All of the mentioned vaccines have proven to be very effective in preventing people from contracting symptomatic Covid-19 and minimizing the chances of hospitalization.
While the different Covid vaccines might work differently and have slightly different efficacies, they will all do the job of protecting you from getting Covid-19 and spreading it to others. This is why it is important to get your doses at the earliest and to take whichever vaccine is available to you. They have all been proven to be safe and effective.
And finally, remember that even after you have been vaccinated, you might still carry the virus. Hence to avoid passing it on to other people who have not been vaccinated, you must still follow the correct Covid protocols, such as social distancing and wearing masks.
