AstraZeneca Thailand revealed the results of a study on the effectiveness of the COVID-19 vaccine. in the area of Chiang Mai Province by a research team from the Faculty of Public Health Chiang Mai University together with the Chiang Mai Provincial Public Health Office and faculty found that the vaccine prevents COVID-19 AstraZeneca’s product is effective in preventing infection with the COVID-19 virus. Omicron species After vaccination against COVID-19 AstraZeneca’s fourth booster vaccine.
However, real evidence from around the world shows that Vaccines against COVID-19 of AstraZeneca The effectiveness of the vaccine (Vaccine Effectiveness (VE)) is 73% (95% confidence interval (CI) 48-89%) in preventing infection with the COVID-19 virus. An omikron species that can spread rapidly. When vaccinated against COVID-19 AstraZeneca’s fourth booster vaccine. regardless of the type of vaccine previously received The researcher stated that The results of this study are the first to assess the effectiveness of a four-dose heterologous COVID-19 vaccine. The results are published in a preprint in Research Square.
However, the research results show that Vaccines against COVID-19 Every fourth booster dose studied was effective in preventing infection with the COVID-19 virus. Up to 75% omicron strains (VE 75%, 95% CI 71-80%) by efficacy of COVID-19 vaccine. AstraZeneca’s rate was 73%, which is about the same as the other mRNA vaccines studied in this study. The efficacy value of the vaccine was 71% (VE 71%, 95% CI 59-79%). The efficacy of the vaccine was adjusted to eliminate influence from variables such as age, gender, calendar time of immunization. and the type of vaccine regimen received previously.
On the side of Dr. Suwat Jariyalertsak Dean of the Faculty of Public Health Chiang Mai University said that this study has shown important information that Vaccines against COVID-19 Fourth needle of any kind It is effective in helping to prevent infection with the COVID-19 virus. A species of omikron that can spread rapidly. Continuous immunization with booster vaccination Therefore, it is important for the at-risk population. especially the elderly group and patients with chronic diseases
The findings also support the effectiveness of vaccination in different cross-formula vaccinations. or mix and match (mix and match), which can help support more comprehensive needle vaccination in the general population.
Mr. John Perez, Senior Vice President Head of Final Development Vaccination and Immunotherapy Department AstraZeneca added that This latest information improves our understanding of the importance of booster vaccines in preventing infection with the COVID-19 virus. in different species from the effectiveness of the COVID-19 vaccine of AstraZeneca in the prevention of severe illness and death
“Now we know that the COVID-19 vaccine of AstraZeneca Can help prevent infection with the virus that causes COVID-19 The Omicron species are good enough. when given as a fourth booster This will be effective in preventing infection with the virus that causes COVID-19. higher after receiving the third booster vaccination,” Mr John said.
In addition, the results of the analysis of preliminary data from the hospital Vaccine Effectiveness Report on Severe COVID-19 Illnesses (patients in need of ventilators) and mortality during severe outbreaks of omikron strains. during Feb. And in March 65, it was found that receiving a three-dose cross-sectional formulation vaccine 98% of severe infections or deaths from COVID-19 were prevented in the population of all ages studied. and only one death in a patient with underlying disease after the fourth booster dose. This indicates the very high efficacy of the vaccine. The analysis of this data set is in the process of collecting data continuously. And all the results will be reported later.
The study reports the effectiveness of the vaccine against COVID-19. of AstraZeneca, CoronaVac and mRNA vaccines using data from a surveillance network from local proactive surveillance. This allows local patient data to be compared. Both during high infestation rates of both delta and omikron species.
“To date, AstraZeneca has delivered more than 3 billion doses of the COVID-19 vaccine from 8 Dec 20 to 8 Dec 20. of AstraZeneca has helped protect more than 6 million lives from COVID-19,” said John.
