Is one vaccine dose enough if you’ve had Covid? What the science says

&gt; Research shows that a previous coronavirus infection plus one dose of vaccine provides powerful protection — but concerns linger<p>This is one thing that’s been incredibly frustrating throughout this whole pandemic. Studies and research will show B, with no sign of A, however inertia&#x2F;politics&#x2F;fear&#x2F;ignorance will continue to push A to the point of harm.<p>An example - a local store was insisting on wiping down the entire checkout conveyor with alcohol between every single customer until very recently, when we’ve know for a long time that you won’t get COVID from that.

&gt; France, Germany and Italy, among other countries, now advise only one dose of vaccine for people with a healthy immune system and a confirmed previous diagnosis. Many scientists who have studied immune responses to vaccination say such policies are a sensible way to make the most of limited supplies in countries that are racing to inoculate their populations.<p>At least for France, their Infectious Disease professionals go further. They&#x27;re of the opinion that a second dose in someone that&#x27;s been infected (within a certain range of time) is subjecting them to unnecessary treatment, wasted time and side effects for no&#x2F;limited benefit.<p>It&#x27;s not to make the most of limited supplies.<p>Auto-translation (with some readability tweaks):<p>&gt; If the second dose of vaccine has already been administered to people with a history of infection with SARS-Cov-2, the data available to date do not show any difference in the safety profile apart from the occurrence of more common systemic reactions.<p><a href="https:&#x2F;&#x2F;www.has-sante.fr&#x2F;jcms&#x2F;p_3237271&#x2F;en&#x2F;strategie-de-vaccination-contre-le-sars-cov-2-vaccination-des-personnes-ayant-un-antecedent-de-covid-19" rel="nofollow">https:&#x2F;&#x2F;www.has-sante.fr&#x2F;jcms&#x2F;p_3237271&#x2F;en&#x2F;strategie-de-vacc...</a><p>But questioning the value of a vaccine under any circumstances is ban-worthy in a lot of places.

Why doesn&#x27;t getting Covid and then allowing your body to produce your own immunity not protect you from getting it again?<p>As I understand the variants are not like the flu or the cold (yet!)

seems like there&#x27;s some consensus on two &quot;exposures&quot; worth of immunity being valuable.<p>any data on second shots for folks who took the J&amp;J?

Natural immunity is way better than any vaccine. You don’t need a vaccine if you already have antibodies.

The study used 26 participants? Did I read that right?<p>What is the preferred sample size to back these sorts of claims?

If infection rates were double digit, the &quot;think of what we could save&quot; argument might perhaps deserve some consideration. But as it stands, I feel the only warranted concern is the well-being of Covid survivors.

I wish there was an easier way to figure out if you had COVID.<p>As someone who&#x27;s only got one dose so far, I would gladly skip the second one if I knew for certain I had COVID before, so someone else could get my second dose.
