Research shows that the two-dose Johnson & Johnson vaccine provides 94 percent protection against coronavirus. Here’s all you need to know about the latest update on covid-19 vaccines.
What is the two-dose Johnson & Johnson vaccine?
Johnson & Johnson released details of three new studies that look at various aspects of its vaccine. Moreover, it shows that they provided long-lasting protection against the COVID-19. However, taking an extra shot can increase the protection. “Our large real-world-evidence and Phase 3 studies confirm that the single-shot Johnson & Johnson vaccine provides strong and long-lasting protection against COVID-19-related hospitalizations,” said Dr. Mathai Mammen. Dr. Mammen is the global head of Janssen Research and Development.
The second phase of trials on the two-dose Johnson & Johnson vaccine shows that receiving two doses 56 days apart provides 100 percent protection from COVID-19. The vaccine also provides 94 percent protection against moderate to severe COVID-19 in the united studies. “Globally, the two-dose regimen provided 75% protection against moderate-to-severe COVID-19,” stated the company. “Hence, among 390,517 vaccinated and 1,524,153 matched unvaccinated individuals. The vaccine effectiveness 79% for COVID-19 and 81% for COVID-19-related hospitalizations,” added the research team.

Moreover, the firm said that adding a booster dose to the single-dose Janssen vaccine increased immunity. “Our single-shot vaccine generates strong immune responses and long-lasting immune memory. And, when a booster of the Johnson & Johnson COVID-19 vaccine is given, the strength of protection against COVID-19 further increases,” explained the firm. “The Johnson & Johnson single-shot COVID-19 vaccine showed vaccine effectiveness against COVID-19-related hospitalizations at 86% for participants younger than 60 years, and 78% for those 60 years and older,” stated the vaccine maker.
Dr. Barouch states that people who got the Janssen vaccine must be reassured by this. “All the vaccines in the US have shown robust and durable protection against severe disease and hospitalization. Ultimately, the job of a vaccine is to keep you from being sick and keep you from going into the hospital and keep you alive. And all of the vaccines are doing that,” he assured.
The researchers also conducted trials in states with a high incidence of the delta variant. “In high-Delta-incidence states, rates of observed COVID-19 were higher in both groups than in the national cohort. In these states, vaccine effectiveness for observed COVID-19 was 79% overall and 78% during June and July. The months where Delta variant incidence was highest,” they added.
