Are the Vaccines Ultimate Answers to COVID-19?
Abstract
According to a report by the Israeli Health Ministry, the efficacy of the US pharmaceutical giant Pfizer's Covid-19 vaccine in preventing infection has dropped to 39 per cent. India has reported a little over 26,000 cases of Adverse Events Following Immunization (AEFI) and 488 deaths linked to post-vaccination complications between January 16 and June 7, according to government data accessed by CNN-News18. Reports exist that the efficacy of these vaccines is not more than 9 months and revaccination may be needed thereafter. As per a report from Ludhiana Tribune, the death caused by the Alfa variant this year was only one while all other deaths were from the Delta variant. To have 100 per cent safety from COVID 19, there is an essential need to eliminate virus. These vaccines are not the ultimate answer to COVID-19 or their variants since they only create immunity and do not eliminate the affecting virus. Further, the variants are also continuously increasing. Nano robots can provide an answer to vaccines. These are already on the threshold and require a concerted effort to make these capable for eliminating corona virus, hence studied here.
