Is immunity from natural COVID infection “better” than vaccine immunity?

Biology/Immunity Vaccines

A: No. Getting vaccinated is by far the safest way to develop immunity to SARS-CoV-2. If you’ve already been infected, getting vaccinated still provides you with the best protection-in fact likely *better* than either previous infection or the vaccine alone. A recent study from Israel created waves with findings that people with previous COVID-19 infection Read more…

Will the COVID-19 vaccines encourage the emergence of new variants or immune evasion?

Biology/Immunity COVID Variants Vaccines

A: No. Vaccines REDUCE opportunities for viral replication needed for variants to emerge. ➡️ TL;DR: The virus has more opportunity to replicate in unvaccinated populations, creating a FAR bigger risk for the development of SARS-CoV-2 mutations. Even so, the good news is that the emergence of variants that fully evade vaccine induced immunity is considered Read more…

How does natural immunity to SARS-CoV-2 infection differ from immunity generated by COVID-19 vaccines?

Biology/Immunity Vaccines

A. COVID-19 vaccines induce higher levels and a broader range of neutralizing antibodies to the receptor binding domain (RBD) of the spike protein than does natural infection. Vaccine-induced antibodies are less likely to be affected by changes in the RBD seen in the current SARS-CoV-2 variants, and are therefore more likely to be more effective Read more…

What is gene therapy? How is it different from vaccines?

Biology/Immunity Uncertainty and Misinformation Vaccines

A: Gene therapies treat diseases using genetic tools. They usually work by making lasting changes to your DNA — the genetic “cookbook” that provides instructions to make you. Vaccines, by contrast, deliver a short-lived signal (e.g. a burst of protein), then disappear. Vaccines and gene therapies both use customized genetic tools to achieve their goals. Read more…

Can COVID-19 cause erectile dysfunction (ED) or affect sperm? (Updated 5/24/21)

Biology/Immunity Clinical Symptoms

A: It’s possible. #VaxUpToGetItUp TL;DR: Due to its impact on inflammation and the vascular system, it is biologically plausible that COVID-19 contributes to erectile dysfunction. But as with much COVID-19 research more, ahem, hard data is needed. COVID-19 infection HAS been associated with a reduction in sperm counts in early research. A recent study found Read more…
