A question about how vaccination influences one’s capacity to serve as a host for the virus. From my, admittedly limited, understanding, the primary benefit of vaccination is reduced chance of “catching” or suffering ill effects from the virus. However, it’s unclear (to me) whether or not a vaccinated individual could still transmit the virus and infect others, if proper precautions were not taken (e.g., wearing masks).
I ask this in response to @Icon’s attempts to caution the elderly to get vaccinated and @Shaun008’s mention of healthcare workers advising the elderly.
The context: my elderly landlord/landlady chatted with me recently and were sad their sons couldn’t visit them (thankfully they work from home, but live in the north). However, I was shocked to hear that the daughter’s visit every week. Both daughters are nurses in hospital settings, but claimed that they could safely visit their parents because they received their first AZ shot.
It’s not really my business, but I advised my landlady that it would be better to wait until she and her husband were vaccinated, since transmission may still be possible, particularly from people working in hospital settings. Of course, the assurances of their nurse daughters greatly outweighed my paranoid concerns.
tl;dr: Is it safe for hospital nurses, with only the first AZ shot to be interacting weekly with their 75+ year-old elderly parents (without masks, obviously).
