Omicron Variants: Do you know about the impact of this on new variants of COVID-19 vaccines?

The new COVID-19 variant, Omicron, has spread rapidly around the world and has been detected in at least 57 countries so far. As far as India is concerned, Omicron cases are on the rise. It is unclear whether the Omicron variant causes milder symptoms than other COVID-19 variants, but much has been said about Omicron’s ability to evade the protective layers of existing vaccines. In a conversation with, Christian Drosten, chief virologist at Berlin’s Charité Hospital, expressed concern at the speed at which the omicron is spreading, as in South Africa and the UK, the number of cases is doubling. three to four days.

Virologists are also concerned that Omicron may escape through the protective layers of existing vaccines. This indicates that people who have been vaccinated and who have also received a booster shot may become infected with the Omicron variant. Some studies represent a strong, approximately 40-fold reduction in the neutralizing effect of antibodies in multiple combinations of vaccination and natural infection. Neither naturally occurring nor vaccine-induced antibodies can prevent the virus from clearing the body’s immune system.

However, vaccine manufacturing companies have issued updates on the ability of their vaccines to fight against the Omicron variant.

Preliminary laboratory studies have shown that serum antibodies induced by the Pfizer-BioNTech COVID-19 vaccine have the ability to neutralize SARS-CoV-2 Omicron variants after three doses. One month after receiving the booster vaccination, the sera obtained from the vaccines neutralized the Omicron variant. Laboratory studies claimed that the third dose would yield stronger protection as it would increase antibody titers by 25-fold.

As for the Moderna vaccine, chief medical officer Paul Burton had said people vaccinated would be protected depending on how long ago they got their shots. During his appearance on the BBC’s Andrew Marr Show, he suggested that the best course of action right now is to take one of the existing COVID vaccines.

So far, there is no reliable information on the severity of COVID-19 disease with Omicron variant as no comprehensive studies or research have been done.
