The health ministry has stated that rapid pace of vaccination and high exposure to the Delta variant could lower the severity of Omicron variant in the country. The ministry is yet to ascertain the scale and magnitude of the rise of the infections, though its spread in India and other countries across the globe is certain.
The Ministry in a statement shared, “Given the fast pace of vaccination in India and high exposure to Delta variant as evidenced by high seropositivity, the severity of the disease is anticipated to be low. However, scientific evidence is still evolving.” The government has re-emphasized on the importance of getting vaccinated.
An introductory study by South African researchers suggests that the Omicron variant is associated with a substantial ability to evade immunity from prior infection. According to the study, the VoC is three times more likely to cause reinfections compared to the Beta or Delta variants. The paper is awaiting peer-approval.
Meanwhile, a study published in The Lancet journal has revealed that six different Covid-19 boosters are safe and elicit strong immune responses in people who have previously received a two-dose course of AstraZeneca or Pfizer vaccines. The most-recent study looked at safety, immune response and side-e effects of seven vaccines when used as a third booster jab. AstraZeneca, Pfizer-BioNTech, Novavax, Janssen, Moderna, Valneva, and Curevac were the vaccines studied.
