I am Covid 19 positive

Ray, I am going to summarize with one liners. Please let me know whether I am on target or not.


4. A vaccinated person with the virus can give it to someone else. That someone else did not benefit at all that the contagious person was vaccinated. Only the vaccinated person stands to benefit from being vaccinated.

I'm interested to see the answer to this question.
I had thought a vaccinated person could not spread the virus.

No vaccine is 100% effective. Covid-19 vaccines are in the 90% range of efficacy. So, vaccinated people do get Covid (termed a breakthrough infection). What we have learned is that when vaccinated people do get it, the disease severity is usually much less severe than for people who are not vaccinated. This is because the viral load in vaccinated people stays much lower compared to the unvaccinated. The flip side of this is that breakthrough cases will spread the disease because these people often won't know they are sick. For most viruses, this is not an issue. But the delta variant is one of the most transmissible respiratory viruses ever seen. So, even a low level infection in a vaccinated person can cause disease in another person.

One thing we are sure of is that viruses can get much more dangerous as they continually mutate and circulate through the population. The longer this goes on, the worse variants we could see.
