Frequently Asked Questions About Immunization Answer – India News

How safe are vaccines?

The three main candidates did not experience significant side effects among the tens of thousands of volunteers who were vaccinated during large-scale studies. Vaccines have been tested in healthy people and more data are obtained from those in vulnerable groups. Regulatory approval processes in India, as well as in advanced markets such as the US and UK, closely examine the side effects and a vaccine is only approved when it is safe and effective by design. Thorough checks are also in terms of production as well as during logistics.

What about allergic reactions reported in other countries?

Cases of anaphylaxis – a severe allergic shock – have been reported from a handful of nearly three million vaccinated people worldwide. Experts have since established that they are due to the fact that people were allergic to certain ingredients in the vaccine, similar to how people might have specific food allergies, but could tolerate most other things. On 30 December, the British authorities updated their recommendations to say that only people with a known history of allergies to any of the vaccine’s ingredients should be careful and that there is no risk to others.

In India, recipients will be monitored for 30 minutes for signs of an allergic reaction, which can normally be addressed quickly.

How soon can I get a vaccine?

If you are a health worker or in a front-line job, such as the police or the army, then you are among the first to receive a dose. After that, people over the age of 50 and those under it, but with comorbid health conditions that make them more vulnerable to Covid-19 will be vaccinated. Together, these groups are expected to represent the first 300 million to be given doses. The government has set a tentative target to complete this process by the summer, which means that if you fall into any of these categories, you can achieve it in the next six months. For others, the wait may be longer and there has been talk of allowing sales on the private market, which could allow people to buy doses at market prices.

Am I safe after the first shot?

Not. People will need to maintain precautions until they receive the booster dose, as all three vaccines approved so far involve a two-dose regimen. Once both doses are given, it can take up to two weeks to build up protective immunity.

How much will he protect me?

It is not yet clear how long immunity to Sars-CoV-2 lasts if it is triggered by a natural infection or a vaccine. Research has shown that antibodies can last for about six months, which reduces the chances of reinfection. But another component of the immune system – adaptive immunity, which also includes memory cells – may be reminiscent of infection for years, as is the case with coronaviruses. This, scientists estimate, can help prevent a serious illness later, even if it doesn’t stop reinfection.

Will the new option make vaccines ineffective?

Vaccines target the spike protein, which includes several of the 17 changes a new mutation has spread widely in the UK and is believed to be more transmissible. However, experts say the changes are not significant enough to keep vaccines out of the question. All major vaccine developers say they are conducting additional tests to determine for sure. But even if a future variant does, vaccines can be quickly redesigned to combat any new mutations that reduce their effectiveness.

Is one vaccine better than the other?

The efficacy rates among the major vaccines had different levels in clinical trials. Their early evaluations also showed that some, such as mRNA platform vaccines, are better than others, such as those using the inactivated virus platform. But all this seems to be above the 50% limit set by regulators for effectiveness. In the initial phase of the launch, experts believe that any vaccine with a level of efficacy above 50% will help slow the pandemic.

How fast can vaccines lead to herd immunity?

This depends on the population of the country. On December 30, Israel vaccinated the largest number of people per capita, with more than seven in 100 people getting the chance, our World Statistics data show. In comparison, the vaccination per 100 people in the US, which has administered 2.13 million doses since December 28, was only 0.64. For a country like India, therefore, the immunity of the herd can last longer. In the meantime, the main goal would be to provide vaccines to those most at risk of death or hospitalization – a cohort that largely includes people in older and comorbid conditions.
