These data further indicate that Covid-19 vaccines offer better protection than natural immunity alone and that vaccines, even after prior infection, help prevent reinfections.
“If you have had Covid-19 before, please still get vaccinated,” said US Center for Disease Control Director Dr Rochelle Walensky. “This study shows you are twice as likely to get infected again if you are unvaccinated. Getting the vaccine is the best way to protect yourself and others around you, especially as the more contagious Delta variant spreads around the country.”
Vaccines provide additional protection against reinfection
The study of hundreds of Kentucky residents with previous infections through June 2021 found that those who were unvaccinated had 2.34 times the odds of reinfection compared with those who were fully vaccinated. The findings suggest that among people who have had Covid-19 previously, getting fully vaccinated provides additional protection against reinfection.
Additionally, a second publication from the Morbidity and Mortality Weekly Report (MMWR) shows vaccines prevented Covid-19 related hospitalisations among the highest-risk age groups. As cases, hospitalisations, and deaths rise, the data in the MMWR reinforce that Covid-19 vaccines are the best way to prevent Covid-19.
Travel to Portugal has recently been made easier as the country has decided to recognise the Indian-produced version of the AstraZeneca vaccine for international travellers. The country originally refused to recognise the Indian-manufactured vaccine Covishield, but now Portugal’s Directorate-General of Health has changed this policy, according to reports.
