Researchers said factors such as testing and lab methods made it difficult to directly compare the CoronaVac results with those of other vaccines
They are investigating how long CoronaVac induces immunity, whether a booster shot will be needed and, if so, the optimal timing of the booster. About 540 participants received a third shot at different intervals – after 42 days, 56 days, 194 days or 208 days – to find out the best regimen for the booster shot. For short intervals of a third shot – 42 days and 56 days after the second dose – the level of neutralising antibodies rose slightly or moderately, according to tests 28 days after the third shot, and they dropped to almost the seropositive cut-off threshold six months later.
“A third dose, given at an interval of six-eight months after the second dose, led to a strong boost in immune response … an increase corresponds to three-five fold increase in neutralising antibody titres 28 days after the second dose, indicating an anamnestic memory B cell response.” Even though the vaccine could induce “memory B cell response”, it was still preferred to induce higher levels of neutralising antibodies for immediate protection.
Researchers said it was difficult to directly compare the estimates in the findings with those of other vaccines such as Moderna and AstraZeneca because of different testing methods, a lack of standardised laboratory methods for coronavirus neutralisation and other issues.
Paid news or study made by China ? lol
My friend wife died after getting 1st shot of Sinovac!!!
MacarioBonifac1 Grabe naman talagang nilunok na nila ang pride para ipaglaban ang Sinovac,..kung yan ay may 97% efficacy rate pwede ko din cguro lunukin pride ko para tangkilikin,..tulad din yan ng Tae sa west phil.sea. SayangPera

Mixed AstraZeneca-Pfizer shot boosts COVID-19 antibody level – studyA mixed vaccination of first AstraZeneca and then a Pfizer COVID-19 shot boosted neutralizing antibody levels by six times compared with two AstraZeneca doses, a study from South Korea showed. That's initial antibodies. In terms of long lasting, T Cell protection then 2 doses of Astrazeneca, 12 weeks apart , is better. Pfizer ($30) are just trying to sell more doses by 'stealing' the 2nd dose. There have not been sufficient safety trials on vaccine mixing, either. wala pa rin vaccine dito 50 ang below ang wala nmn mga wokes na reklamador tulad sa pinas at divisve na chismis agency tulad ng rappler Why not get two shots of Moderna? I confirm that ten shots of Pfizer will produce more antibodies than two shots

Antibodies from Sinovac's COVID-19 shot fade after about 6 months, booster helps – study(1st UPDATE) Philippine Health Secretary Francisco Duque says there is no recommendation yet from the country's vaccine expert panel on giving a booster shot but experts are discussing the possibility Hirap p nga kau s 1st dose!!! Same experts that recommends use of face shields? They are probably afraid of angering those in govt who promoted Sinovac. But if they care for their fellow Filipinos and for the HCWs who got Sinovac, they should make the call and do it early. These people are most vulnerable thinking they have protection when they don't.

Antibodies from Sinovac's COVID-19 shot fade after about 6 months, booster helps - studyAntibodies triggered by Sinovac Biotech's COVID-19 vaccine declined below a key threshold from around 6 months after a second dose for most recipients, although a third shot had a strong booster effect, according to a lab study. Duque said there is no recommendation yet from the vaccine expert panel but discussing the possibility on giving a booster shot..” HUNGHANG! 1st shot nga kapos pa aarya ka na naman!
