I think its arguments are really flawed and not grounded in reality but like I said, I do not think that convalescents should vaccinate but I think they should be highly encouraged to have a booster shot because it about halves the change to become reinfected.
I think that this discussion if previously infected should or should not be vaccinated has generated just too much distraction.
Even in EU, where one, who had PCR test confirmed infection, can get COVID-19 certificate for 6 months (compared to 12 months for double vaccinated, now 9 months), it has given the anti-vaxxers too large platform.
They would not have gained it without this mistake in politics.
