My Patients Ask — Will the COVID vaccine protect me from the dangerous delta variant?

The Delta variant, also known as B.1.617.2, was first detected in India but has since surfaced in more than 70 countries. The CDC says the COVID Delta variant poses a growing threat in the U.S. because it is more contagious than other strains and produces more serious symptoms. That’s the bad news.

The good news is that our current COVID vaccines are extremely effective against this and almost all other variants recognized so far. For example, the Wall Street Journal (Subscription Publication) reports separate studies from researchers in the U.K. and Scotland suggest that currently authorized COVID-19 vaccines offer significant protection against the Delta coronavirus variant.

Reuters reports, “COVID-19 vaccines made by Pfizer and AstraZeneca offer high protection of more than 90% against hospitalization from the Delta coronavirus variant.”

Public Health England (PHE) – in a preprint analysis – “said that the Pfizer/BioNTech COVID-19 vaccine was 96% effective against hospitalization from the Delta variant after two doses, while Oxford/AstraZeneca’s offered 92% protection against hospitalization by Delta.”

Reuters adds that the PHE findings follow a Scottish research letter published in The Lancet “which showed that two doses of a COVID-19 vaccine among people who tested positive cut their risk of hospitalisation by 70%.”

COVID variants are such a powerful argument to get vaccinated. If you’ve had your first dose of an mRNA vaccine (Moderna or Pfizer), make sure you get that second dose. And for those who have not been vaccinated yet, please get vaccinated.

Much of the focus right now is on the existing variants. But the more that the novel coronavirus is allowed to spread, the more chances it has to mutate.

As a result, until or unless we reach herd immunity in the U.S. for COVID, we can expect that there will be other variants that will arise, spread, and become of concern.

This blog was accurate as of the day of posting. However, as the COVID-19 pandemic rapidly evolves and the scientific community’s understanding of the novel coronavirus and the COVID vaccine develops, the information above may have changed since it was last updated. While I aim to keep all of my blogs on COVID and the COVID vaccine up to date, please visit online resources provided by the CDC, WHO, and your local public health department to stay informed on the latest news.
