The vaccine will also need to be tweaked to cover new coronavirus variants as they emerge.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">The advantage of mRNA vaccines like Pfizer\u2019s is they are much easier to update than the \u201cviral vector\u201d vaccines like AstraZeneca\u2019s. We should still use AstraZeneca now for over-50s, but our best long-term strategy is to use mRNA COVID-19 vaccines,<\/span><\/p>\n<p><!--more--><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Long term immunity to coronaviruses does not last.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">We know our immunity to different coronaviruses wanes over time.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Israel said, according to Reuter, it will begin offering a third dose of Pfizer\u00a0vaccine to adults with weak immune systems but it was still weighing whether to make the booster available to the general public.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Our immune system is a complex network of cells and proteins that defends the body against infection. It protects the body from intruders, such as bacteria and viruses.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">It has two parts-innate and adapted.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">A important part played by the immune system is to keep a record of all microbes that have attacked and defeated previously, so it can recognize and destroy the microbes, including viruses quickly when it enters the body again.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Our immune system orchestra is composed of:<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">white blood cells- B cells-the leader of the orchestra, T cells, Plasma cells, , memory B cells derived from the activated B lymphocytes, T cells and, macrophages<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Macrophages-these are specialized cells involved in the detection, phagocytosis and destruction of bacteria, viruses, and other harmful organisms.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">They also present the foreign offenders like the viruses to the T cells and initiate inflammation by releasing molecules known as cytokines.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Others in the orchestra are- antibodies formed by plasma cells<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">lymphatic system<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">spleen<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">bone marrow<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">thymus.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">White blood cells \u2013 the key players made from the stem cells in the bone marrow and in the lymphatic system.

These are the memory cells that form the part of the adaptive immune system.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">B lymphocyte cells perform two important functions:<\/span><\/p>\n<ol style=\"text-align: justify;\">\n<li><span style=\"font-size: 20px; color: #000000;\">They differentiate into plasma cells and produce antibodies.<\/span><\/li>\n<li><span style=\"font-size: 20px; color: #000000;\">They can present antigen to helper T cells<\/span><\/li>\n<\/ol>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Helper T cells with the appropriate receptor binds to the presented antigen, COVID virus in this situation.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Plasma cells release antibodies.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">These antibodies are able to bind to the same antigens as the receptor on the B cell that was originally activated.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">After you had the first jab from any type of Covid-vaccine-Pfizer, Moderna, AstraZeneca, among others, the body response in your immune starts cracking.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">The B cells maturing in the bone marrow or in the lymph nodes gets stimulated by the Helper T cells to proliferate and differentiate into Plasma cells and memory cells.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">The maturation of the B cells starts in the bone marrow and travel to the spleen for the final step of maturation into mature memory B cells.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">\u00a0Memory B cells can\u00a0<strong>survive for decades<\/strong>, which gives them the capacity to respond to multiple exposures to the same antigen- the virus.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Vaccines against Coronavirus do not prevent or cure COVID , but still beneficial.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">While a major achievement, none of the vaccine candidates in circulation can entirely prevent the virus from entering the body, nor stop its transmission. But according to a new computational analysis, outright prevention or cure may not be the be all and end all.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">The research, led by Bruce Lee, Professor of Health Policy and Management at City University of New York, suggests that a vaccine or viral treatment that can shorten the infectious period of COVID-19 by just half a day for 25% of confirmed cases could avert up to 1.4 million infections and more than 99,000 hospitalisations.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">According to Australia\u2019s COVID-19 Vaccine Roadmap released last week, priority population groups, including GPs, are set to receive the Pfizer\/BioNTech candidate, which has an efficacy rate of 95%. The majority of the population, however, will receive the University of Oxford\/AstraZeneca candidate, which, based on current data, has an efficacy rate of 70%.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">\u00a0The modelling would suggest a lower efficacy rate could still have significant benefits in curbing the pandemic. But it may take longer to achieve the end goal of elimination, according to Professor MacIntyre.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">\u2018It is important that people understand that vaccination is absolutely important but also that it\u2019s not a panacea.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">WHO urges fully vaccinated people to continue to wear a mask?<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">Those recovered from COVID-19 had a robust antibody response after the first mRNA vaccine dose, but little immune benefit after the second dose, according to new research. The findings suggest only a single vaccine dose may be needed to produce a sufficient antibody response.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 20px; color: #000000;\">\u00a0Those who did not have COVID-19 did not have a full immune response until after receiving their second vaccine, reinforcing the importance of the two recommended doses.
