23 Jul 2021 – <\/strong><\/em>The Latest Data from Israel and the UK on Covid Vaccine Effectiveness<\/strong><\/h3>\n<\/blockquote>\n

The latest data from Israel<\/strong>, which has used primarily the Pfizer mRNA vaccine, indicates that<\/a> vaccine effectiveness against Delta coronavirus infection and symptomatic (\u201cmild\u201d) disease has dropped from about 95% to about 40%, whereas effectiveness against hospitalization and severe disease (i.e. low blood oxygen levels) remains at 80% to 90% (see chart above).<\/p>\n

Importantly, in people who got vaccinated already in January 2021 (primarily the elderly), protection against infection and mild disease may already have dropped to near 0% (see chart above). Moreover, since the Delta covid outbreak is still accelerating in Israel, the effectiveness against hospitalization and severe disease may further decrease (due to lags in hospitalizations).<\/p>\n

In the UK<\/strong>, which has primarily used the AstraZeneca DNA adenovector vaccine, the latest estimate by researchers at the University College London indicates an effectiveness against infection of close to 0%<\/a> and an effectiveness against severe disease of about 60%<\/a>. In very senior citizens, the effectiveness against severe disease may be even lower (due to a weaker immune response).<\/p>\n

(A substantially higher estimate<\/a> by Public Health England, recently published in the New England Journal of Medicine, was based on outdated data from early June. Interestingly, the British government hasn\u2019t updated its data on AstraZeneca vaccine effectiveness since June 13.)<\/p>\n

The Israeli data shown above indicates that effectiveness against infection and symptoms decreases rapidly over time and reaches near-zero levels after about half a year. Most likely, this is because covid vaccines do not achieve mucosal immunity<\/a> (in contrast to natural infection) and serum antibody levels (i.e. antibodies in the blood) decrease within months<\/a>.<\/p>\n

Thus, the false promise<\/strong> of very high protection against \u201csymptomatic infection\u201d, found during official vaccine trials, was simply based on very high short-term serum antibody levels mimicking mucosal immunity. The pharmaceutical companies probably even knew that this was just a (very lucrative) \u201cflash in the pan\u201d and not a lasting protective effect.<\/p>\n

In contrast, protection against severe disease<\/strong> is achieved by lower serum antibody levels<\/a> in combination with immunological memory<\/a> (B cells) and cellular immunity (T cells). However, the Delta variant has already achieved partial immune evasion<\/a> (as did Beta and Gamma, but not Alpha), and future coronavirus variants will likely achieve almost complete immune evasion.<\/p>\n

Thus, vaccine protection even against severe disease will likely further decrease due to new variants<\/strong>, or, in the very worst case, will turn into antibody-dependent disease enhancement<\/a> (ADE), if high levels of non-neutralizing antibodies aggravate the infection. Indeed, this is what happened in the case of vaccines against SARS-1 and dengue fever.<\/p>\n

To prevent such a decrease in protection against severe disease, or to restore short-term protection against infection and mild disease, updated booster shots will likely become necessary.<\/p>\n

However, there is a very real risk<\/strong> that additional vaccinations, which inject or induce the coronavirus spike protein, could substantially increase the risk of serious cardiovascular and neurological adverse events<\/a>, such as strokes, GBS and heart muscle inflammation. Globally, covid vaccines may already have killed tens of thousands of people<\/a>. Alternatives include safer oral vaccine candidates<\/a> or medically supervised, low-dose oral live virus challenges in low-risk people.<\/p>\n

Furthermore, the millions of people who were told that vaccination will protect them against a coronavirus infection will soon have to realize (once again) that this is not the case: instead, most of them will get infected anyway. On the positive side, this may actually provide additional mucosal immunity to large parts of the population (while being protected against severe disease.)<\/p>\n

Indeed, data from Israel<\/a> as well as recent studies<\/a> all indicate that a previous coronavirus infection continues to offer the best protection against future infections and disease.<\/p>\n

In contrast, vaccination cannot achieve \u201csterile immunity\u201d (against infection and infectiousness). Thus, the whole idea of \u201cvaccination certificates\u201d<\/strong> is obsolete<\/a> \u2013 at least from a medical and epidemiological perspective \u2013 and should be rejected by authorities or the people<\/a>.<\/p>\n

For instance, just this week a \u201cfully vaccinated\u201d Australian managed to pre-symptomatically infect about 60 people<\/a> at a party in the United States. Many similar stories have already been reported in Europe and Israel<\/a>: fully vaccinated people can easily transmit the virus even to large groups. Hence, imposing \u201cvaccination certificates\u201d or \u201cgreen passes\u201d could only serve a\u00a0political purpose<\/a>.<\/p>\n

In many countries, mass vaccination campaigns<\/strong> have themselves triggered<\/a> large coronavirus outbreaks (\u201cpost first dose spike\u201d<\/a>), possibly due to a combination of vaccine-induced temporary immune suppression and infections at large indoor vaccination centers visited by thousands of people. The vaccine-induced temporary immune suppression may also explain the frequently observed post-vaccination appearance of shingles<\/a> (i.e. herpes zoster reactivation).<\/p>\n

Concerning children<\/strong>, since covid remains mostly asymptomatic or mild in them anyway, and since vaccination cannot prevent infection and infectiousness, the vaccination of children and even of young low-risk adults becomes increasingly difficult to justify, especially given the very real vaccine-associated cardiovascular risks<\/a> to them (e.g. teen myocarditis and cerebral blood clots).<\/p>\n

A look at covid data in places like Israel, the UK and Portugal<\/strong> \u2013 which were first in Europe to experience the Delta variant summer wave \u2013 confirms that, while infections have skyrocketed, hospitalizations have remained rather low and deaths have remained very low so far (see charts below). In contrast, in countries with a low vaccination rate<\/strong> \u2013 such as India, Russia, as well as many Asian and African countries, Delta covid deaths have reached all-time record levels (see below).<\/p>\n

In conclusion<\/strong>, and as argued previously<\/a>, vaccine protection against infection and \u201cmild disease\u201d has pretty much collapsed, whereas protection against severe disease and death remains at a reasonable level, with the partial exception of the most senior citizens and especially nursing home residents, some of whom have never mounted<\/a> a neutralizing antibody response to the vaccine. Moreover, future coronavirus variants will likely achieve additional immune evasion<\/a>.<\/p>\n

Given the current situation and outlook, it may once again be emphasized that research and implementation of early treatment options for high-risk patients<\/a> \u2013 especially anti-viral, immuno-modulatory and anti-thrombotic treatment \u2013 should be a top priority.<\/p>\n
