Dr Manoj Singh, consultant chest and critical care, Apollo Hospital, Ahmedabad, told this newspaper: “The vaccine’s efficacy is never guaranteed. As a result, delivering a booster dose will not provide 100% protection. Preparing a vaccine takes a long time, at least three to four years to ensure adequate coverage. We’re all in a situation where vaccines are administered to individuals and the effects of the doses are being studied.”
He further added, “Since Omicron is being studied, scientists may prepare a vaccine later that helps to fight the infection. We may have achieved cross-immunity, if not herd immunity.”
He also proposed that instead of waiting for the booster shot, people could get flu shots, which protect against multiple strains of the seasonal flu virus. He further recommended that the second dose be taken right away while adhering to the protocols and taking the necessary precautions against the virus.
