How Long Does it take to Build Immunity After COVID-19 Vaccination?

While India recovers from the second wave of Covid-19’s devastation, preparations for a probable third wave are being made through improving health infrastructure. On June 23, India reported 50,848 new cases in the previous 24 hours, bringing the total number of cases to over 30 million and the death toll to 3,90,660.

However, according to the Ministry of Health and Family Welfare website, the vaccination effort has gained up steam in India, with a total of 29,46,39,511 doses administered until June 23. This means that 3.8 percent of India’s population has been fully vaccinated, while 15% have received their first dose since the vaccination push began in January.

As part of its goal to vaccinate all of its inhabitants by the end of the year, India has licensed three Covid-19 vaccines: Bharat Biotech’s Covaxin, Serum Institute of India’s Covishield, and Russia’s Sputnik V. All three vaccines are two-dose vaccines with different gaps between the two doses.

According to the federal government, a gap of 12-16 weeks between Covishield doses, 4-6 weeks between Covaxin doses, and 21-90 days between Sputnik V doses is appropriate. It takes a few weeks for each of them to build immunity after the initial shot. Because vaccinations are still relatively new and we are still discovering how they work to generate immunity, the most common question is how long does it take to build immunity after receiving a vaccination?


  • As state-run hospitals fall behind, the government establishes a maximum monthly limit for vaccine stockpiles at private clinics

  • According to the National Institutes of Health, India’s Covaxin effectively neutralizes the Delta variant of Covid

According to Dr Katherine O’Brien of the World Health Organization, a decent immune response takes two weeks to kick in after the first dosage, and the second dose amplifies that first immune response, making immunity stronger in a shorter amount of time.

Covid-19 vaccinations train human immune systems to recognize and fight viruses by infusing comparable virus responses into the body. Because immunity takes two weeks to form, a person could still become sick after receiving the vaccine.
