Covid-19 vaccines and vaccinations

Yes, I've got something at the moment that might be another round of Covid. Can't be sure, but I and several others have had a raised temperature, which isn't especially common with colds.
 
I went to the walk-in pharmacy yesterday to get both the Covid and flu vaccines, but was disappointed that my province didn't receive the flu vaccines yet. So I only got the Covid jab. The pharmacist asked me if I had any infections recently, mainly EBV, which was the first time I've been asked this. I do feel "viral" in the last week, but answered no, and no on the form.

I really wish people like Dr Elisa Perego on X would stop spreading this information and continuing to make connections b/c it's really not helpful.
 
Acute infection as a driver of chronic diseases and the unsung benefits of vaccination, 2026, Cheon et al.

Cheon, In Su; Esser, Mark T.; Sun, Jie

Acute infections can leave durable biological imprints that alter host physiology, chronic disease susceptibility, long-term health and even biological ageing, well after pathogen clearance.

Vaccines should therefore be evaluated not only on their ability to prevent acute illness, but also on their efficacy in preventing or mitigating these long-lasting biological imprints and infection-associated chronic conditions.​

I was supposed to get both too last week, but they'd run out of Covid. They said pop back any afternoon, but I need to find a day when I can definitely rest for the following one or two if necessary. I don't usually get many after-effects, but it's always possible.
 
Low levels of influenza and increasing 4.9% since last week. Low levels Covid and decreasing 1.2% since last week.

I should have called before I went in yesterday, and waited until both were available. Now I don't feel like going back for the flu jab. The walk-in pharmacy was empty when I was there so at least I didn't have to wait long.

I've started wearing my mask.
 
My son got both his Covid and flu vaccines last week. I was concerned about him taking them both at the same time as he typically flares from vaccine, but other than temperature regulation the next day and some increased joint pain for a couple days, he did well with no big crash. He had the Sanofi Novavax vaccine as the side effects from the Moderna and Pfizer shots are always really bad for him. This one is much better for him (I find the same).
 
From the Limitations:
The analysis did not account for any (averted) downstream health consequences following acute respiratory infection, such as cardiovascular complications [Citation53] or post-acute sequelae such as long COVID [Citation54], nor did it include informal productivity losses. These omissions may have led to large underestimations of the benefits of vaccination given the substantial burden of post-acute respiratory infection [Citation55], and because the modeled population is weighted toward older adults, many of whom contribute to the economy via unpaid or informal labor.

The socioeconomic value of adult respiratory vaccination in Australia: a benefit-cost analysis, 2026, Napier et al.
Napier, Matthew; Macfarlane, Angus; Tunnicliffe, Ellie; Brassel, Simon; Cahill, Camilla; Ryan, Sally; Lohan, Christoph; Struwig, Valda; Vietri, Jeffrey; Mendes, Diana; Hu, Tianyan; Steuten, Lotte

ABSTRACT​

Background​

Pneumococcal disease, respiratory syncytial virus, influenza and COVID-19 cause a major burden of illness and death among adults, much of which is vaccine-preventable. We estimated the societal value of adult vaccination against these four pathogens in Australia.

Research design and methods​

We developed disease-specific static life table cohort models and conducted a societal-perspective benefit-cost analysis of adult respiratory vaccination, approximating those recommended by the Australian Technical Advisory Group on Immunization, relative to no vaccination. Mortality risk reductions were monetized using value of a statistical life (VSL) and value of a statistical life year (VSLY); avoided morbidity and productivity losses were also captured. Main outcomes were benefit-cost ratios (BCRs) and net monetary benefits (NMBs).

Results​

Over ten years, age and risk-based vaccination generated gross returns of $11.24 (VSL) and $5.69 (VSLY) per Australian dollar invested (net returns $10.24 and $4.69), with NMBs of $64.97 billion and $29.76 billion, averting 234,187 hospitalizations and 13,890 deaths. BCRs remained well above 1 across all scenarios.

Conclusions​

Adult respiratory vaccination shows strong societal returns. Improving coverage and extending eligibility offer the potential for further societal gains. Some simplifications in the model are likely to understate the value of vaccination while others may overstate it.

I got the Covid vaccine three weeks ago, but the flu vaccine wasn't available at that time So I went back to the walk-in pharmacy last week with a friend to get the flu vaccine but they told me they don't give vaccines on Sundays :emoji_disappointed: I'm not going back. I had a dental appointment yesterday and I was so afraid I would get the flu since it's pretty high in my area.
 
Stronger flu shot linked to nearly 55% lower Alzheimer's risk

Date: November 7, 2026

Source: University of Texas Health Science Center at Houston

Summary: A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who received a high-dose influenza vaccine had a nearly 55% lower risk of developing Alzheimer's, compared with a 40% reduction previously associated with the standard-dose vaccine.

In a large study led by researchers at UTHealth Houston, adults ages 65 and older who received a high-dose influenza vaccine were less likely to develop Alzheimer's than those given the standard-dose version. The findings, published in the medical journal Neurology, suggest that the strength of a flu vaccine could matter for more than just protection against influenza.

Autopsy findings after SARS-CoV-2 vaccination: a German national registry study, 2026, von Stillfried et al.

Abstract
Autopsies are the foundation of evidence-based medicine and gold standard for determining causes of death. A potential causal relationship between COVID-19 vaccination and death remains a subject of debate, however multidisciplinary, multicentric national autopsy studies are missing.

N = 486 eligible SARS-CoV-2 vaccinated autopsy cases from 14 German pathology, neuropathology and legal medicine university centres between 2021 and 2024 were available via the German National Autopsy Registry.

For comparison COVID-19 autopsies were included (n = 385 cases, all performed before the vaccination campaign in Germany started). A previously established causality algorithm was applied in a consensus assessment of potential causality between vaccine administration and an adverse event following immunization (AEFI). N = 176 cases with a post vaccination interval ≤ 28d were included into analyses.

In a single case of allergic reaction, in 5/8 cases of either myocarditis (n = 4 cases) or perimyocarditis (n = 1 case), and 9/26 cases of thromboembolism, the consensus process resulted in a potential AEFI in these cases, but no definite causality. In n = 3 cases in which the cause of death remained unclear after autopsy, no potential AEFI could be established. In SARS-CoV-2 positive autopsy cases without vaccination, thromboembolism was documented as cause of death in 18/385 cases and myocarditis in 2/385 cases.

In conclusion, autopsies are a valuable tool to assess adverse effects. Currently, post vaccination autopsy numbers are too low to draw conclusions on the general population or to identify rare AEFI signals. As part of pandemic preparedness, international guidelines for post vaccination autopsy procedures, diagnostics and interpretation are necessary. Autopsy registries can support this collective effort.
