Well, to start, there is no vaccine against COVID-19, or even any treatment thats been shown to be effective. Pneumonia on the other hand, whilst potentially fatal, has vaccines. This is a big difference in COVID and other disease.
there is also no vaccine for many strains of the flu (which is a bigger killer by a factor of thousands) or for the common cold for that matter, both of which can cause pneumonia, covid doesn't kill you in any different way to any other respiratory condition, it gives people with compromised immune systems or other serious underlying problems pneumonia.
in the last week of january alone a touch under 10,000 people were diagnosed with flu in just the uk, a small percentage of them will die, why has this not made the news? why is the country not in a state of mass hysteria over flu?
