Jakarta, Beritasatu.com – The number of sufferers and deaths due to Covid-19 in Indonesia it is still increasing. Vaccines or vaccinations are necessary to control these conditions. Because in addition to protecting yourself, vaccination can break the chain of transmission of the SARS Cov-2 virus that causes Covid-19 through the formation of community immunity or herd immunity.
Chairman of the Indonesian Technical Advisory Group on Immunization (ITAGI), Prof. Sri Rezeki Hadinegoro, said vaccines work to reduce the risk of infection by training the body’s immune system to recognize and fight pathogens (viruses and bacteria). Vaccines will destroy specific immunogens for each antigen or other microorganism that will produce an immune response.
Someone who has been vaccinated or immunized about 80% to 95% can avoid the disease, but for himself. In order to prevent transmission in the community, the key is that immunization coverage must be high, at least 80% or more.
“If the disease is very contagious, then the vaccination coverage must be very high, above 80% or up to 100% before it can be cut off. For example, polio has 100% coverage, but other diseases that are not very contagious, 80% coverage is sufficient to stop disease transmission, “Sri said at a virtual media socialization event” vaccination for the country “held by KPCPEN together with the Ministry of Communication and Information, Saturday (31/10) .
According to Sri, vaccination coverage Covid-19 must be high to form immunity or collective immunity in the community. This collective immunity occurs when most residents have immunity or immunity to the virus. Even though only 80% of the residents were immunized, 20% of the other residents were automatically protected. This is what is called herd immunity.
What often becomes the question is whether vaccination is necessary, because if a person is infected with a virus, the community will form self-immunity. According to Sri, community immunity can occur from two aspects. First, let the many who are infected because after a long time there will be community immunity. Second, community immunity can be formed by vaccination.
In fact, according to Sri, there is no need for immunization if everyone follows the health protocol with discipline. As in Malaysia and Thailand, the decline in cases was quite fast because health protocols were implemented with discipline. The problem is that in Indonesia there is a lack of discipline on health protocols, so that transmission and spread is high. Therefore, it is impossible if Covid-19 infection is left without prevention by vaccination.
“Are we waiting for all the residents to get sick? If everyone is sick and if they are isolated they can still be at home, that’s fine, but if everyone needs treatment at the hospital, they need an ICU, use a ventilator, die, the doctors are overwhelmed, the hospital is full, is this what we want, “said Sri.
