I thought that was a spoof account?
Back to Trish Greenhalgh (who is disturbingly very real), I see she is retweeting misinformation, such as this:
The immune system is not like a muscle. You don't have to pump it in the gym to keep it strong. Repeated infections with COVID are severe and WEAKEN the immune system. We keep STRONG by NOT GETTING INFECTED WITH COVID.
And also stating anti-vaccine misinformation herself, such as this:
UK's in a mess because a) masking's been abandoned, b) vaccination immunity is waning (+many people had Astra-Zeneca which waned more than most), c) indoor mass events -> mixing.
The truth is very different to what people like her portray

If a vaccinated individual is reinfected later, the memory B and T cells proliferate and virus-specific antibodies and T cells are produced. The memory response takes several days and therefore infection is not prevented. However virus reproduction in the immunized host is substantially reduced and severe disease does not occur...
..After multiple COVID-19 vaccines received emergency use authorization, studies in several countries were done to determine if immunity prevented infection. When the studies were done shortly after vaccination, antibody and T cell levels were high, and infection was prevented. But as the immune response waned (see figure above), vaccine efficiency against infection declined. This observation was incorrectly interpreted by many to indicate that the vaccines were failing. Largely ignored was the fact that vaccinated individuals were still protected from developing serious COVID-19 disease and death...
Vaccines remain effective where it actually matters; exposure to Coronaviruses does build up natural immunity; repeated exposure does act as a natural booster. We see this already for similar viruses such as OC43 and SARS-COV-2 is not fundamentally different.
Amusingly, people who side with her, or Eric Ding & co tend to use the argument "you aren't a virologist" against anyone who challenges their misinformation.
My response to that is: I am not. I never claim to be. Neither are you. And neither are the experts you listen to. But I do listen to
actual virologists and immunologists, who are well respected and not attention seekers.
A big problem with social media is that those who shout the loudest get huge followings of misinformed people.
While a small number of people will get ill, for the vast majority of people there is absolutely nothing to be concerned about and we can live our lives completely normally.
Vaccines are intended to allow us to lead normal lives. It's absurd for restriction activists to attempt to undermine their effectiveness in order to justify their proposed restrictions on others.
I will stop debunking these people when the media stops listening to them; until then, I will continue to do so.
