Jakarta, CNN Indonesia –
Corona virus vaccine trials (Covid-19) by Johnson & Johnson showed a positive response. Preliminary results from phase 1/2 a clinical trials indicate that this drug is well tolerated, and even one dose can produce a strong immune response in nearly 800 participants. clinical trials.
Quoted from CNN, The trial was conducted in two age groups, namely 18-55 years and 65 years and over to see the safety and side effects of the two different doses. The preliminary findings of trials show that the vaccine can trigger an immune response from the virus.
In addition, this vaccine is also considered safe enough to proceed to large-scale trials. The study was posted on MedRxiv, but has not been further reviewed or published in a medical journal.
The researchers found that 99 percent of participants aged 18-55 years in both dose groups had developed antibodies to the virus 29 days after being vaccinated. The analysis found that most of the side effects such as fever, headache, body aches disappeared after a few days.
Participants will later receive a second injection of vaccines as part of the trial. As is known, the vaccine developed by Johnson & Johnson uses the same technology to develop vaccine candidates for Ebola, Zika, HIV and RSV.
Furthermore, a phase 3 trial is planned to examine the safety and effectiveness of a single dose against placebo for preventing symptoms of Covid-19.
For the phase 3 trial, Johnson & Johnson plans to recruit 60,000 volunteers at more than 200 locations in the United States and globally. According to Chief Scientific Officer Dr. Johnson & Jhonson Paul Stoffels’ single dose trial should have further accelerated the findings.
So far, Johnson & Johnson is the only party testing the Phase 3 covid-19 vaccine in the US. The company said stricter vaccine guidelines were being considered by the US Food and Drug Administration.
Meanwhile, Director of the US National Institute of Allergy and Infectious Diseases, Anthony Fauci, said that the Covid-19 vaccination could most likely begin in November or December 2020.
However, he said conditions could return to normal by the end of 2021.
“When there are enough people being vaccinated, you will start to think that things will return to normal. Maybe (it can get back to normal) in the third quarter or the fourth quarter of 2021,” Fauci said.
Fauci added, it is unlikely that there will be political interference in the Covid-19 vaccine approval process. “If you look at the standard process of how these things work, I think you can feel good about how these things are so unlikely to happen,” he concluded.
