5 things we are sure you didn’t know about Covid-19-related herd immunity
Coronavirus is not undefeatable, and there are ways where people can work together to achieve full eradication, such as preventive measures or herd immunity. Different methods require varying approaches, but herd immunity is a term not exactly very clear to many in the masses. Many people across the world also looked for herd immunity, especially after COVID-19 was announced as a pandemic. A lot of short news apps also discussed the subject in detail. In order to understand how herd immunity in COVID-19 can be achieved, let’s look at what herd immunity is, and how it works.
What is Herd Immunity?
Herd immunity has become a highly discussed topic amid COVID-19 pandemic. As per its concept, if a certain percentage of people are immune and the number is high enough, the outbreaks could, in theory, start to subside. If you imagine an area with 100 houses in a city wherein an outbreak is confirmed. If you place a concentrated population of people immune outside the area as a border, they could act as a transmission barrier.
How does it work?
It depends on different real-life situations, but the idea is that people who are immune can be spread out into areas and they can border the outbreaks to help curb them for implementing herd immunity for Coronavirus. The idea here is to make a few people immune with the help of a vaccine, who are strategically chosen to prevent outbreaks from spreading. This is the most spoken-about method, as the vaccine availability is still a huge question, and it remains uncertain if it will be enough to cover everyone. herd immunity is also being tested across many places worldwide, with implementation by those already once infected.
What are the Requirements?
All that is needed to try out herd immunity in COVID-19 is a certain population which is immune, and a strategic plan to place such people amid the masses. Since there is little actual proof of auto-immune responses, either a person infected in the past or a vaccinated person can be included in the herd immunity threshold. When it comes to theoretical models, any number of possibilities is true, as there are various factors which remain undetermined. These include an uneven disease spread and even the possibility of herd immunity being achieved by itself.
Issues and Concerns on Herd Immunity
People are asking questions about herd immunity’s efficacy, and if it would work at all. In theory, if the threshold is reached, it could definitely work to protect society. The next issue raised by many on herd immunity in COVID-19 is about how to make people immune for the threshold, as there are two possibilities. First one is vaccination, which is yet by far unavailable, and the next one is the immunity of those already infected, which sees doubts if it lasts forever, and if not, then for how long. Many are also sceptical about its overall efficiency, and if it would help in a smaller time frame.
How Can it be Achieved?
Despite challenges, if masses in any given geo-reference point plan it accordingly, herd immunity approach, coupled with other precautionary measures, can be achieved. If we plan daily movements in the public and surround areas with those who are immune, the approach can work. Imagine a hypothetical scenario, wherein you consider an area of 500 houses in a city with high infection rates. If people, sitting at homes under limited restrictions collaborate with each other, they can formulate a plan to achieve herd immunity for COVID-19. If there are around 1,500 people, and 100 have already been infected and recovered, they are technically immune, even if for a limited time.
These recovered people can now work with other residents and move around and about to help other people with the outdoor tasks such as bringing items of daily need and groceries, sanitization of public areas, handling emergencies such as helping residents with visits to the doctor, etc. Since the outdoor movement is limited to only those who have been recovered, chances are, that they could avoid the virus from spreading into the local area even though the city’s infection rates are high.
In the end, herd immunity for COVID-19 is a matter of coordinated effort, which could be boosted by the arrival of a vaccine, and would, to some extent, require support by authorities in some cases. The challenges we face are many, but solutions are being worked upon, and in the meanwhile, staying alert and adhering to all prevention and precautionary measures has proven to be helpful.
