The expected news about the vaccine that will give hope to the world has arrived!

The expected news for the updated vaccines for Omicron’s sub-variants BA.4 and BA.5, which has become the dominant variant in most countries and can evade existing vaccines, came today. The US Food and Drug Administration (FDA) is expected to approve new coronavirus vaccines this week. So how did new vaccines get approval so quickly? Here is the answer to the question everyone is wondering…

While we are preparing to breathe a sigh of relief in the coronavirus pandemic that has turned our lives upside down for two years, Omicron’s sub-variants BA.4 and BA.5 once again became a cause for concern for all of us. .

With the discovery that BA.4 and BA.5, which are highly contagious and have become the dominant variants in most countries, managed to get rid of both natural immunity and the immunity provided by the vaccine, vaccine manufacturers rolled up their sleeves again.

While both Moderna and Pfizer-BioNTech are adapting their current vaccines according to Omicron, the expected news for the vaccines that everyone has been eagerly waiting for came today.


The U.S. Food and Drug Administration (FDA) is expected to approve new coronavirus vaccines this week, according to a new report by the Wall Street Journal.

The new vaccines contain the same ingredients as existing coronavirus vaccines, with only a few minor changes to act on the Omicron variant. For this reason, approval processes have progressed faster than previous vaccines.

Moderna has announced that it will be able to supply the vaccines in the next few weeks. However, it is not yet known which countries these vaccines will be applied to.


Without waiting for these vaccines to be tested on humans, the FDA will use data from experiments on mice.

FDA Commissioner Dr. “The evidence from existing mRNA Covid-19 vaccines administered to millions of people shows us that the vaccines are safe,” said Robert Califf.

Emphasizing that updating existing vaccines to protect against different strains does not require a change in vaccine content, Califf stated that this is a common practice in flu vaccines;

“The FDA has extensive experience in reviewing strain changes in vaccines, as does the annual flu shot.”

The European Medicines Agency (EMA) announced that the updated vaccines will be approved by autumn.


An intense vaccination campaign is expected to begin next fall, with both Moderna and Pfizer-BioNTech’s updated vaccines approved for the Omciron variant.

The UK has become the first country to approve a vaccine developed by the US-based company Moderna against both the original coronavirus and the Omicron variant of the virus.

Following Moderna, Pfizer is expected to begin human trials later this month.

Professor William Schaffner of Vanderbilt University pointed out that clinical trials take a long time to run.
