Two good friends of mine are dead of the virus. A close relative's career as a pilot was cut short from the cognitive effects of long COVID. Virus particles don't float around by themselves, they are carried in droplets of mucous and sputum from the respiratory tract. And the best masks, when worn only by one person, were only ever given a 20% chance of stopping an infection for contact within 6 feet for more than 5 minutes. Masks on both parties and greater than 6 foot separation was substantially more effective. Your problem is that you seem to think that unless some specific measure can guarantee absolute protection from the disease than it is worthless. The COVID vaccines have saved millions of lives. Your final comment is absolute bullshit. Thousands have not died from the vaccines.Scientists don't start arguments with insults, so we can disqualify you as having any worthwhile opinion on the matter.
No there isn't. The exact opposite. Any immunologist will tell you the best vaccine is to actually GET the infection, people under 65 were at minimal risk of dying from covid anyway, much less kids, and nearly all masks worn were wholly incapable of stopping something as small as a virus, toots. Even the whole 6 foot thing was completely arbitrary. The one thing certain now is that the covid vaccine as offered was nothing but a huge money-making scam without the research or development to make it safe, and thousands paid the price.
