According to recent research from a pharmaceutical company, people who receive a booster shot with Johnson & Johnson vaccine are better protected against coronavirus for a longer period of time.

It was found that one dose of Johnson & Johnson vaccine protects 66% against the development of severe COVID-19 in the whole world and 72% protects against such cases in the United States. But when a person receives a booster shot two months after the first, protection rises to 94%. And booster vaccinations six months later will result in a 12-fold increase in antibody levels.

Experts have long stated that people will need additional COVID-19 shots in the future because the effectiveness of vaccines currently available, including the two-dose Pfizer and Moderna vaccines, has waned over time. Johnson & Johnson research data confirms that the COVID-19 booster can go a long way in providing ongoing protection against the virus.

“Our one-shot vaccine generates a strong immune response and long-lasting immune memory. And when the Johnson & Johnson booster vaccine is given, the strength of protection against COVID-19 increases even more,” the company said.

Pfizer data shows that booster shots can increase vaccine efficacy by up to 95%. The third dose of Moderna vaccine, given six months after the first two doses, also significantly boosts immunity, according to the company.

Health officials have already recommended a third shot of the Pfizer or Moderna vaccine for high-risk Americans — the immunocompromised and the elderly.
