COVID-19 vaccines from Vietnam proven safe during trial – Nano Covax and Covivac have been proven safe and effective during its first two clinical trials.
The COVID-19 vaccines from Vietnam were given to 551 volunteers during its second trial. This includes 281 volunteers from Long An and 271 from Hanoi while the others were given Covivac shots which are still in their first stage.
The Nano Covax trials have been ahead of the schedule and according to the Military Medical University, volunteers who have received two shots of Nano Covax during the second stage were all in normal conditions.
Albeit a few suffered from swelling and muscle joint pain, they have felt better after resting.
After the first clinical trial of Nano Covax, all volunteers who participated during the trial were reported safe and produced high concentrations of antibodies. Thus, the COVID-19 vaccines from Vietnam proved effective even on the new variants of SARS-CoV-2 which are found in the UK.
During the second stage of the trial, the vaccination has expanded to elderly and those with suspected underlying diseases. Around 108 senior citizens were treated including the oldest which is 76 years old.
These senior citizens have only shown few to no reactions and with no unusual symptoms.
The results of the second trial of the Nano Covax will be announced in late April and will enter its third clinical trial in the first week of May.
Looking at the initial results of the first two stages of trials, experts are confident that the third stage will be completed at the end of the third quarter which is three months early based on the initial schedule.
On the other hand, the vaccine developed by the Health Ministry’s Institute of Vaccines and Medical Biologicals – Covivac is in the first stage of its clinical trial done by the Hanoi Medical University’s Centre of Clinical Pharmacology.
66 volunteers were vaccinated since March 15 who had experienced slight swelling within the injected part and headache but later on disappeared after 24 hours.
The other 54 volunteers will be injected between April 7 to April 14, 2021. Following the 28 days interval, the six volunteers who have been injected last March 15 were scheduled to the second shot on April 12.
