COVID-19 vaccine was effective against the delta variant in a laboratory

Moderna’s COVID-19 vaccine proved to be effective against variants, including the highly contagious and rapidly spreading delta variant, according to the company Tuesday.

Moderna reports that the mRNA vaccine produced neutralizing antibody after two doses against both delta and the beta and eta versions first discovered in South Africa and Nigeria.

The vaccine was not as effective against some South African beta variants than the ancestral strain.

Data that was not peer reviewed used serum samples taken from eight participants one week after the second dose of COVID-19 vaccine. The results may not be representative of the actual effectiveness of the vaccine in the real world because they were based on laboratory testing.

“We must be proactive in our efforts to end the pandemic. These data are encouraging and strengthen our belief that the Moderna COVID-19 vaccination should continue to protect against new variants,” Stephane Bancel, CEO of Moderna, said in a statement.

Moderna announced the announcement on the same day that its vaccine was granted emergency use authorization in India. This is where the Delta variant is believed to have caused a large outbreak.

It is rapidly spreading. It is estimated to be the most prevalent strain in the world and accounts for around 20 percent of U.S. cases. All available vaccines in the United States are effective against the Delta variant. However, the threat to those who aren’t vaccinated is grave.

Last week, the World Health Organization advised caution and recommended that everyone, including those who are fully vaccinated continue to wear masks and keep physically away from crowds.

Mariangela Simao (WHO assistant director-general, access to medicines, and health products), said that vaccines alone will not stop community transmission. She was referring to regions like Latin America where there is a high level of community transmission.

“People should continue to use masks, keep in ventilated areas, practice hand hygiene, and avoid crowding,” Simao said. Simao stated that this is still vital, even if you are vaccinated.

The Centers for Disease Control and Prevention (U.S.) have stated that fully vaccinated individuals do not require masks and should not be concerned about the delta variant.

Although access issues, vaccine hesitancy and refusal are still major obstacles in the U.S. it is unlikely that leaders will reimpose mandates for masks or distancing requirements. Experts expect localized spikes in areas with low vaccination rates and urge everyone to get vaccinated.
