>> Maybe the best strategy for herd immunity would be to get double vaccinated to prevent serious effects then contract Covid to gain superior antibody response

From reading about Covid, I thought the virus had a couple of genes that make it more deadly, one of which tends to suppress the immune system for example. Why not create another variant that is a full virus without those genes and use that as a live vaccine? Sure it might escape, but so what it's less lethal than the one out there right? Obviously this raises a bunch of ethical issues, but they are similar to the issues around forced vaccination.
- vigilantmav 5y agoWhat you are talking about is actually a type of vaccine. https://en.wikipedia.org/wiki/Attenuated_vaccine https://en.wikipedia.org/wiki/Attenuated_vaccine My guess is that such a vaccine would take longer to develop, but I'm not sure about that. Wiki also lists the following drawbacks: In rare cases, particularly when there is inadequate vaccination of the population, natural mutations during viral replication, or interference by related viruses, can cause an attenuated virus to revert to its wild-type form or mutate to a new strain, potentially resulting in the new virus being infectious or pathogenic.[34][39] Often not recommended for immunocompromised patients due to the risk of potentially severe complications.[34][40][41] Live strains typically require advanced maintenance, such as refrigeration and fresh media, making transport to remote areas difficult and costly.[34][42]
