NHS doctor challenges health secretary over Covid vaccination rules
This bit is quite enlightening from Javid in response to the doctor.
James replied: “Maybe there is an opportunity to reconsider with Omicron and the changing picture, or at least the nuance that will allow doctors who have had antibody exposure, who’ve got antibodies, who haven’t had the vaccination, to not have it,
because the protection I’ve got is probably equivalent to someone who is vaccinated.”
“
Yes, but at some point that will wane,”
Javid said.
Which will mean as the doctor said,
"James said: “But if you want to provide protection with a booster you’d have to inject everybody every month. If the protection has worn off for transmission after two months then after a month you’ve still got a bit of protection. But if you want to maintain protection you’re going to need to boost all staff members every single month, which you’re not going to do.”
Javid answered his challenge by saying: “We take the very best advice that we can, from vaccine experts.”
Half a day after the video was published on Twitter, it had been watched about 1.2m times".
Prior infection or being vaccinated does not guarantee that you'll not get infected with covid. Prior infection immunity will work exactly as vaccine induced immunity unless you have a weakened immune sytem. Antibodies will 'wane' but they turn into memory cells that lodge in the lymph glands waiting until you get infected again then they spring into action.

Memory Cells
If your body fights a virus once, the same
virus will probably try to attack again. After all the work it took to get rid of that first infection, it would be a shame to have to do it all over again. An amazing feature of your immune system is that it remembers the infections it has fought. This makes it much easier to fight the same virus or bacteria a second, or third, or fourth time.
A Memory cell never forgets
Toward the end of each battle to stop an infection, some
T-cells and
B-cells turn into Memory T-cells and Memory B-cells. As you would expect from their names, these cells remember the virus or bacteria they just fought. These cells live in the body for a long time, even after all the viruses from the first infection have been destroyed. They stay in the ready-mode to quickly recognize and attack any returning viruses or bacteria.
Quickly making lots of antibodies can stop an infection in its tracks. The first time your body fights a virus, it can take up to 15 days to make enough antibodies to get rid of it. With the help of Memory B-cells, the second time your body sees that virus, it can do the same in thing 5 days. It also makes 100 times more antibodies than it did the first time. The faster your body makes antibodies, the quicker the virus can be destroyed. With the help of Memory B-cells, you might get rid of it before you even feel sick. This is called gaining immunity.
This graph shows how Memory Cells help you to better fight infections. At day 0, someone catches a virus. At day 10, her B-cells start making antibodies, and by day 15 she’s made enough antibodies to destroy all the viruses. Now, she doesn’t make any more antibodies, so fewer and fewer are left in her body. At day 40, the same virus gets in her body again. Since she has Memory B-cells prepared to fight, she can quickly make 100 times more antibodies than she did during the first infection.
Building Memory Cells without getting sick
If you get an infection, you can build up immunity to that specific virus. Another way to get immunity is to get a vaccine. Vaccines are very weak or dead versions of a virus or bacteria that prepare your Memory Cells to fight that specific virus or bacteria. Since vaccines help you gain immunity without getting sick, they are especially good protection for very dangerous illnesses.
Vaccinations in history
The first successful vaccine was against smallpox in 1796. Smallpox is caused by a very contagious and deadly virus. Back then, smallpox was especially scary because people knew so little about viruses, bacteria, or how the immune system works.
It was Dr. Edward Jenner who noticed that young women who milked cows usually caught cowpox, but rarely caught smallpox. He thought maybe getting cowpox prevented getting smallpox.

Cowpox virus |
To test his idea, Dr. Jenner tried infecting people with cowpox on purpose, and then exposed them to smallpox. Amazingly, they didn’t catch smallpox. He didn’t know exactly how it worked, but we now know that cowpox and smallpox have antigens with similar shapes. This means that Memory Cells to fight cowpox can also fight smallpox. Because
vacca means cow in Latin, Dr. Jenner called this type of disease prevention vaccination.
After Dr. Jenner’s discovery, it became common to vaccinate everyone against smallpox. It has been so successful that since 1979 there have been no smallpox infections.
Today, we have many vaccines to protect us from getting sick. Most of these are shots, but some scientists are working on vaccines made in plants that you can eat. This might mean one day you won’t get a vaccine shot, you’ll just enjoy a vaccine smoothie!"
There has been loads of care staff sacked, because they haven't had the vaccine but have had Covid. Unnecessarily, they've been forced to leave their care jobs even though they have as much chance of catching covid, have as much protection, and are as likely to pass it on, as those who've had a vaccine. If you can take a lateral flow test to get into an event then the same should apply to those in the NHS that are not vaccinated, as it should have done for care workers.
Maybe there isn't a 'shortage' of care workers because Johnson's '20 000 strong care worker army' are filling the vacancies of those sacked. He'll need far more than 20 000 to cover those in the NHS that will be forced to leave their jobs even though they've had Covid and are not vaccinated. Or maybe they'll do a u-turn and start asking if people have had a prior infection or are prepared to take lft tests constantly and therefore able to keep their jobs.
