Jakarta, CNN Indonesia –
Head of the Laboratory of Applied Genetic Engineering and Design Protein LIPI, Wien Kusharyoto explained the reason red and white vaccine for corona vaccine Covid-19 requires two injections to be effective against the virus.
Wien says the first injection is to trigger an initial immune response. The second injection can strengthen the immune response that has been formed
“The first injection is to trigger an initial immune response to the vaccine given. The second injection can increase the strength of the immune response that has previously been formed,” said Wien when contacted. CNNIndonesia.com, Thursday (10/9).
In line with Wien, the Special Staff of the Minister of Research and Technology / Head of National Agency for Research and Innovation, Ekoputro Adiyajanto said that two shots made the vaccine’s efficacy even higher.
Eko explained that the formation of antibodies to fight the virus depends on what is called the efficacy of the vaccine.
“Of course the vaccine’s efficacy is expected to be higher. This can only be seen after going through various stages of development to clinical trials,” said Eko.
Eko explained that the formation of antibodies to fight the virus depends on what is called the efficacy of the vaccine.
The WHO recommends an efficacy of at least 50 percent on a 100 percent efficacy scale. In addition, vaccines must also form antibodies after vaccination.
“If you say a vaccine with 50 percent efficacy and antibodies is formed well after vaccination, then maybe a person is vaccinated only once. However, if it is safer, it is better that in a certain period each person is vaccinated twice,” said Eko.
Two doses of vaccine are judged to be reasonable doses. Some vaccines such as chickenpox, hepatitis A, shingles (shingles) also require two doses of the vaccine to prevent the disease. Some vaccines require even larger doses, such as the DTaP vaccine for diphtheria, tetanus, and pertussis.
Previously, Bill Gates stated that everyone needs several doses of the corona vaccine to provide immunity from Covid-19 due to infection with the SARS-CoV-2 corona virus.
The man who became the founder of a humanitarian foundation engaged in the health sector, Bill and Melinda Gates Foundation, said that the Covid-19 vaccine currently being developed is not expected to give optimal results if given only once.
So, this former Microsoft boss reminded the importance of mass production of the corona vaccine. Because, everyone around the world will need more than one shot of the vaccine.
