Russia is claiming a successful vaccine & plans producing asap vaccination front line health workers first. What could go wrongLatest published evidence retesting people that had the Rona is that their antibodies against CoVid 19 they had after recovering only remain at the same strength in 17% after 3 months. Many have no antibodies left. That suggests no immunity and no protection if they were reinfected.
It's worse in human vaccine trials where there aren't high levels of antibodies or in the recently published Oxford human trials only around 45% of subjects developed immunity, although this increased to around 57% if they were given two doses of the vaccine. There were also many reported side effects htat another medication have to be given for.
This is the vaccine trial that progressed to human subjects after 100% failure in the rhesus monkey trials where they all got the virus.
The other human trial recently reported was the US Moderna backed trials that Trump has poured 100s of millions into, recently published initial results showing that the vaccine worked to trigger an immune response with mild side effects -- fatigue, chills, headache, muscle pain, pain at the injection site. The Phase 1 study included 45 healthy adults, ages 18 to 55, who received two vaccinations of the mRNA-1237 vaccine candidate 28 days apart.
There is no information about how many subjects produced antibodies to the virus. "We thought the immune responses look promising, but we don't know whether the levels we're seeing would actually protect against infection. It's really hard to know that until you do the actual efficacy trial," said Dr Lisa Jackson.
They are looking to enrol 30,000 adults for Phase 3 studies.
However with the published results that immunity doesn't last in subjects who developed antibodies naturally, which in every other disease case is longer lasting than a vaccine, is changing human RNA an acceptable risk?.
