AAQ, I’m not sure about traditional vaccines, but cell based vaccines (which all covid vaccines currently are) do not produce b and t memory cells while natural immunity to covid does.
Your family being sick for months is exactly why lockdowns and social distancing is not a solution to preventing the spread of viruses. Immune systems grow weaker with masks, social distancing, and lockdowns. People should build up their immune systems naturally, not weaken their immune system by staying away from society or being injected with experimental vaccines. I do understand why older people would want to take the covid vaccine (personally I would not choose to do so would I be over 65 years of age), but I’m totally against mandatory vaccination.
