Side effects after Pfizer COVID vaccine more common after COVID-19
Patients with a history of COVID-19 were more likely to have side effects after their first dose of the Pfizer/BioNTech COVID-19 vaccine than those who were never infected, according to a Vaccine study yesterday.
The researchers conducted a prospective observational study consisting of 311 healthcare workers from a university tertiary care hospital in France. From Jan 27 to Feb 5, they self-reported demographics and symptoms 21 to 28 days after their first vaccination and before their second.
The mean age was 55.4 years, and 60% of respondents were women. Twenty (6.4%) had a history of COVID-19, and 19 were symptomatic, but none were hospitalized. The mean duration between COVID-19 infection and their first vaccine dose was 10.3 months.
About 74% of participants (229) had at least one side effect, affecting 95% of those with prior COVID-19 and 70% of coronavirus-naive recipients. Systemic reactions, which 37% experienced, were most commonly fatigue (18%), headache (14%), and muscle pain (20%). Of the 66% who had a local reaction, site injection pain was more frequent than erythema (skin redness; 63% vs 8%). No side effects required additional medical attention.
"Vaccine recipients with prior COVID 19 infection experienced systemic side effects with a significantly higher frequency than naive patients," write the researchers. "However, symptom intensity was not different between the 2 groups, [except] for headache." Three of six people with headaches who previously had COVID-19 had severe headaches, compared with 3 of 37 people without prior infection.

Malnutrition linked to worse COVID-19 outcomes
Adults and children with COVID-19 and a history of malnutrition may be more likely to die of their infections or need mechanical ventilation, according to a study yesterday in Scientific Reports.
The researchers looked at 8,604 children (mean age, 6 years) and 94,495 adults (mean age, 53 years) hospitalized with COVID-19 across 56 US hospitals from March to June 2020 and compared those with a malnutrition history from 2015 to 2019 with those without. Twenty-one children and 4,706 adults died.
Children with malnutrition made up 7.5% of severe pediatric COVID-19 cases (39 of 520) and 1.5% of mild pediatric COVID-19 cases (125 of 7,959). As for adults, those with malnutrition made up 4% of severe COVID-19 cases (453 of 11,423), and 1.8% of mild cases (1,557 of 81,515).
Overall, 1.9% of pediatric patients (164) and 2.1% of adult patients (2,010) in the cohort had a history of malnutrition.
Data indicated that children older than 5 and adults ages 18 to 78 with previous malnutrition were more likely to have severe COVID-19 than the same age-groups without. While children younger than 5 and those older than 79 had higher odds of severe COVID-19 if they were not malnourished, the researchers say this could be due to a lack of medical data and a general high risk for COVID-19 infection, respectively.
"Emphasis has been placed very early into the pandemic on the impact of age and comorbidities on the risk of severe COVID-19 and obesity has been the focus of the nutrition conversation," the researchers write.
"This study established that the long-term effect of (or preexisting) malnutrition is also a critically important piece of the puzzle. While the COVID-19 pandemic may lead to increased incidence of malnutrition, malnourished patients or patients at risk of malnutrition are also at risk of suffering more severe forms of the disease."
