Anti-bodies could be destroyed before the third wave


Susmita Nandi: DNI, Vaccination for health workers began in January Vaccination for people over 60 was limited to April, but experts say antibodies do not last more than six months, but doctors say a third wave will arrive in September-October. Concerned doctors and health workers who received the vaccine fear they may be unable to keep covid away from them.
Some have mentioned that vaccines will provide potency that can help keep the epidemic at bay.  AIIMS Delhi director Randeep Guleria has called for a ‘second-generation booster dose’ to counter the third wave. Apollo Gleneagles Hospital consultant oncologist Subir Ganguly said, “Most of us were inoculated by February-March so many of us might have suffered an antibody depletion. It may not be uniform for everyone but since we will be at the forefront yet again, let us assume that we are back to the pre-vaccination period. But whatever be our immune status, vaccination has managed to pull down the death rate so it will help to curb the intensity of the disease.”
According to Rahul Jain, antibodies deteriorate over time, and that can be a cause for concern for doctors. “It’s bound to be less effective for many of us now,” said Jain. Others like Peerless Hospital microbiologist Bhaskar Narayan Chaudhuri, said, “Usually antibodies don’t last more than six months. Those who received their vaccines within February-March could be at risk during the third wave. But their infections are likely to be mild due to T-Cell immunity which lasts long.”
