Pediatric Hexavalent Combination Vaccine Vaxelis Now Available - Clinical Advisor

Vaxelis™ (diphtheria and tetanus toxoids and acellular pertussis, inactivated poliovirus, Haemophilus b conjugate and hepatitis B vaccine) is now available in the United States. 

Vaxelis is the first hexavalent combination vaccine indicated for active immunization to prevent diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, and invasive disease due to Haemophilus influenzae type b. The vaccine is approved for use as a 3-dose series in children from 6 weeks through 4 years of age (prior to the 5th birthday). The 3-dose series consists of a 0.5 mL intramuscular injection administered at 2, 4, and 6 months of age.

Vaxelis has been included as a combination vaccine option in the Centers for Disease Control and Prevention's (CDC) recommended 2021 Child and Adolescent Immunization Schedule. Three doses of Vaxelis constitute a primary immunization course against diphtheria, tetanus, H. influenzae type b invasive disease, and poliomyelitis; however, the 3-dose series does not constitute a primary immunization series against pertussis as an additional dose of pertussis-containing vaccine is needed to complete the primary series. Vaxelis may be used to complete the hepatitis B immunization series.

Vaxelis is contraindicated in patients with a history of a severe allergic reaction to any other diphtheria toxoid, tetanus toxoid, pertussis-containing vaccine, inactivated poliovirus vaccine, hepatitis B vaccine, or H. influenzae type b vaccine. It should not be administered to patients with a history of encephalopathy within 7 days of a previous dose of a pertussis-containing vaccine or to those with a history of progressive neurologic disorder, including infantile spasms, uncontrolled epilepsy, or progressive encephalopathy until a treatment regimen is established and the condition is stabilized.

"As the first 6-in-1 vaccine in the US, Vaxelis is now available to help protect infants and children against diseases caused by 6 infectious agents," said Elaine O'Hara, Head of Sanofi Pasteur Commercial Operations North America. "Studies have shown that combination vaccines may help reduce the shot burden and improve coverage rates and timeliness."

Vaxelis is supplied as a suspension for injection (0.5 mL dose) in single-dose vials and prefilled syringes.

Roseola vs. measles rash: What is the difference? - Medical News Today

Image
Roseola and measles are two different diseases that present with a high fever and a rash. They are both most commonly seen in childhood, although measles can affect people of any age, and roseola in adults is very rare. While both diseases share similarities, there are distinguishing factors, such as how the symptoms present and the disease progression. Read on to find out the difference between roseola and measles rashes. Roseola, also known as roseola infantum, sixth disease, or exanthema subitum, is a viral infection that typically affects children. The human herpesvirus 6 (HHV-6) or human herpesvirus 7 (HHV-7) causes roseola. The disease is spread through tiny respiratory droplets that people either breathe in or pick up from surfaces they touch. This disease usually presents in children between the ages of 6–12 months . Children who have this disease experience a high fever, followed by a pink or red rash. Roseola is a self-limiting viral illness, meaning it will typically go awa...

Coronavirus fake news echoes century-old polio fears - Newsroom Coronavirus fake news echoes century-old polio fears - Newsroom Posted: 05 Feb 2020 08:32 AM PST FEBRUARY 6, 2020 Updated 15 hours ago Dr Heather Battles Dr Heather Battles is a lecturer in anthropology at the University of Auckland and researches infectious diseases and epidemics. Show more Ideasroom During the past month, in the confusion and uncertainty over the precise origin of the 2019 novel coronavirus outbreak, many alternate ideas or 'conspiracy theories' have sprung up and spread widely via social media including Twitter and Facebook. I have had a sense of déjà vu as many of these claims have parallels in how people responded to another 'emerging' epidemic disease a century ago: polio. The first example that struck me is the idea (spread by US fake news website Infowars and others) that the roll-out of 5G technology is to blame, wit...
