A variant strain of coronavirus spread to a nursing home with 90% of the elderly vaccinated

An unvaccinated staff member in a US nursing home became infected with a mutated strain coronavirus and then an explosion was recorded in covid-19 cases in the nursing home, despite the fact that more than 90% of its occupants were vaccinated.

According to the Centers for Disease Control and Prevention (CDC), the virus then spread to the Kentucky Retirement Home, infecting 44 people, 24 residents and 20 staff members, 18 of whom received two doses of the Pfizer vaccine, respectively. against covid-19.

This study demonstrates the limits of vaccination as the only coronavirus treatment strategy, mainly against its variant strains, as noted by AMPE.

Although “vital”, vaccination should be accompanied by “continued care in infection prevention and control practices,” as the authors of the study point out. hand washing, the continuous conduct diagnostic tests to detect cases of covid-19, the quarantine of patients and their contacts and these “regardless of vaccination”.

The CDC study also looked at how vulnerable people are to those infected with covid-19 depending on whether or not they have been vaccinated.

Among nursing home residents infected with the variant strain, only one-third of those vaccinated showed symptoms, compared with 83% of those who were not vaccinated. And only 11% of those vaccinated had to be hospitalized, compared to two-thirds of those who were not vaccinated.

Finally, only one vaccinated resident of the 18 infected became dead. Of the six unvaccinated, two succumbed to covid-19.

“In order to protect the residents of the nursing homes, it is necessary for their staff as well as the residents to be vaccinated,” the authors of the research underline.
