Post-vaccination, those reinfected may have milder symptoms: Guleria

Even as chances of reinfection with Covid-19 are low, vaccination against Covid-19 is likely to protect people from severe symptoms if a fresh infection occurs after the immunity from the vaccine lapses, says AIIMS director Dr Randeep Guleria. He said long term studies will be required to assess how long immunity lasts among vaccinated people. But, even in case of reinfection, it is more likely to be mild. Doctors said the immunity from the current vaccines may last for 9-12 months. However, since these are current generation vaccines, both efficacy and immunogenicity of Covid vaccines are likely to improve in future.
