While some lucky people claim to have never had COVID, many are facing our second, third or even fourth infection, often despite having been vaccinated. You might be wondering, how long does immunity last after a previous infection or vaccination? Let's take a look at what the evidence sho...
Can you become immune to COVID-19? Patients who recover from COVID-19 make antibodies to the virus that may impart immunity for at least 6 months; however, breakthrough infections do occur and may be more likely with newly circulating variants of the virus. Immunizing with the latest recomm...
If you’re one of the millions of Americans who have already had Covid-19, you may be wondering how long you will have immunity from the coronavirus. Earlier in the pandemic, most people assumed that getting infected had at least one upside: that you would be protected against future encou...

“We know that vitamin D is an immunomodulator, so low levels of vitamin D could inhibit immunity and allow the inflammation to become rampant.” Does having low vitamin D increase your risk of catching COVID-19? Studies have linked low vitamin D levels with hundreds of diseases, including ...
An important factor in achieving herd immunity against SARS-CoV-2 (the virus that causes COVID-19) is is how long the vaccines protect you.
Having compared the levels of anti-rAd26 viral vector NAbs before the vaccination and the titers of RBD-specific IgGs one month later, baseline anti-Ad26 NAb levels were concluded not to affect the anti-SARS-CoV-2 immunity elicited upon a single-dose Gam-COVID-Vac vaccination. Importantly,...
Many of the tools and behaviors that help protect against infection can still help you avoid reinfection, Dr. Abu-Raddad said. “There is no magical solution against Covid reinfection.” 阿布-拉达德说,许多感染防护的手段和行为同样也可以用于避免再感染。“对于新冠再感染,并没有什么特别神奇的解决办...
Such observational studies give real hope for the durability and potential of protective immunity. We still have much to learn about the immunology of COVID-19, but the pace of research is astounding, and the more we learn, the more we are empowered to beat this virus. Our immune system ...
