Vaccine Verification App Bureaucratic Mess
Travel during the Covid-19 pandemic has created a bureaucratic mess, especially for those who venture outside the country. It’s now routine overseas for unvaccinated individuals to have to jump through more hoops and restrictions than vaccinated travelers do
In practical terms, whether you will need to use a vaccine verification app will largely depend on where you’re going and how you’ll get there.
There have been reports of myocarditis or pericarditis in adults and young people aged 12 years and older after they receive a Pfizer vaccine or a Moderna vaccine. This appears to occur more commonly in men.
Vaccination certificates are nothing new. They are health documents that record a vaccination event – traditionally as a paper card – with key details including the date, product and batch number of the vaccine administered.
Following viral entry, COVID-19 infects the ciliated epithelium of the nasopharynx and upper airways.
One common symptom, loss of smell, results from infection of the support cells of the olfactory epithelium, with subsequent damage to the olfactory neurons. The involvement of both the central and prepheral nervous system in COVID-19 has been reported in many medical publications.  It is clear that many people with COVID-19 exhibit neurological or mental health issues. The virus is not detected in the CNS of the majority of COVID-19 patients with neurological issues. However, SARS-CoV-2 has been detected at low levels in the brains of those who have died from COVID-19, but these results need to be confirmed. While virus has been detected in cerebrospinal fluid of autopsies, the exact mechanism by which it invades the CNS remains unclear and may first involve invasion of peripheral nerves given the low levels of ACE2 in the brain. The virus may also enter the bloodstream from the lungs and cross the blood-brain barrier to gain access to the CNS, possibly within an infected white blood cell.
