The study shows vaccinated people tolerate Covid much better than unvaccinated.That doesn’t seem so critical with current variants, most people are handling them without too much discomfort. But should a more virulent strain emerge it could be very helpful.
That said, apparently new vaccines that are better targeted to expected strains, should be available soon…so probably wise to wait a bit. Here’s the study summary:
‘ Overall, these data strongly support the impact of SARS-CoV-2 vaccine boosters on diminishing SARS-CoV-2 disease severity and symptoms. Vaccine protection from any SARS-CoV-2 infection wanes over time, in part due to new variants propagated by immune escape [2, 3], yet the vaccine-booster was strongly associated with less severe symptoms at baseline as well as over 14 days of illness, even when adjusting for viral variants. SARS-CoV-2 vaccination, with the development of a primed immune response, is likely the best single prophylatic treatment for COVID-19 to prevent clinical deterioration and decrease symptoms. With vaccination or survival of prior infection, COVID-related mortality becomes less of a concern; however, the morbidity of symptoms does remain a concern. Symptoms such as loss of sense of smell or taste affect quality of life. Vaccine boosters appear to be the single best strategy to ameliorate symptom severity, and this reflects a possible important clinical benefit of vaccine boosters even for those at low risk for hospitalization due to severe COVID-19.’
