Summary from a LANCET paper

• Prior infection with COVID-19 protects most people against reinfection, with 0.65% of patients returning a positive PCR test twice during Denmark's first and second waves, compared with 3.27% of people who tested positive after initially being negative.
  
• People over the age of 65 are at greater risk of catching COVID-19 again, with only 47% protection against repeat infection compared with 80% for younger people.
  
• Protection against reinfection remained stable for more than six months.
  
• The findings underline that measures to protect the elderly - including social distancing and vaccinations are essential even if people have already been diagnosed with COVID-19.
  
• The analysis focused on the original COVID-19 strain and made no assessment of variants.
  

Again not one or zero thing.

It increase protection but you can still get reinfected.

After some time the protection weakens.

Many disease like mumps and measles you get one time and lifetime protection.

This covid is blardy tricky beast!

You can get the infection but your body will know how to fight it. The memory of how to fight is long-term. This will reduce the virus load.

Not true.
Provided your memory cells dont die or lose memory.
Some ppl more prone to kena infected probably the memory cells has aging or defecting.

Just imagine if a wise person can live forever.
Human being will be invincible.
Same as our memory cells, they have life span.
It just that it has longer life span than normal human cells.

Meaning those older people and those with poor immunity, vaccination will work much less efficiently. It is more important to eat a healthy diet, sleep well and exercise regularly. Together with practice like wearing proper mask and avoid crowded places.

Still have to depend on your memory cell life span.
Can you imagine if your memory cell can live up to 80years old. No bacteria or virus can harm your body.

Someone is injected with Hep. B vaccine, more than 20 years later, it still can be detected. Was shock when the researcher told me there is a present of these in your blood. She said you had been injected with Hep. B vaccine before.

It is the ability of the body to fight the virus. When you are old, the fighting is slow. For young people, one knock, the other person collapses on the floor. For old people, one knock, the other person can fight back. Booster shot can be like yearly in-camp training. But when you are old, nobody want you any more.
