We present two cases of shoulder pain and weakness following influenza and pneumococcal vaccine injections provided high into the deltoid muscle. Based on ultrasound measurements, we hypothesize that vaccine injected into the subdeltoid bursa caused a periarticular inflammatory response, subacromial bursitis, bicipital tendonitis and adhesive capsulitis. Resolution of symptoms followed corticosteroid injections to the subacromial space, bicipital tendon sheath and glenohumeral joint, followed by physical therapy. We conclude that the upper third of the deltoid muscle should not be used for vaccine injections, and the diagnosis of vaccination-related shoulder dysfunction should be considered in patients presenting with shoulder pain following a vaccination.

Although previous studies have shown either no association between immunisation and SIDS or even a decreased risk of SIDS, adverse effects, including death, from immunisations continue to cause concern, especially when a new vaccine is introduced. ⋯ This study provides further support that immunisations may reduce the risk of SIDS.

The WHO Steering Committee reviewed and evaluated the progress towards global control of measles and rubella and provided guidelines for future research activities concerning both diseases during its meeting in New Delhi, in April 2005. Global measles vaccination coverage increased from 71% in 1999 to 76% in 2004 and indigenous transmission was interrupted or kept at very low levels in many countries. However, Africa and Southeast Asia continue to experience endemic transmission and high mortality rates, despite a global mortality reduction of 39% between 1999 and 2003. ⋯ RT-PCR was considered as an alternative method for laboratory diagnosis of CRS. The value of dried blood spots and oral fluid as alternative samples for measles and rubella IgG and IgM detection and genotype determination was evaluated. However further validation of these methods in different settings is required before their routine use can be recommended.

Randomized Controlled Trial Comparative Study
A controlled clinical trial comparing the safety and immunogenicity of a new adjuvanted hepatitis B vaccine with a standard hepatitis B vaccine.
A randomised trial was conducted in 285 adults not immune to hepatitis B (HB) to compare the safety and immunogenicity of a commercial aluminium-adjuvanted HB vaccine with and without an additional new adjuvant (AgB/RC-210-04 or AgB study groups, respectively). The additional adjuvant RC-529 is a fully synthetic monosaccharide mimetic of monophosphoryl lipid A. Subjects in the AgB/RC-210-04 (n=136) and AgB (n=149) groups were vaccinated intramuscularly on days 0, 30, and 180, according to the standard vaccination schedule for hepatitis B vaccines. ⋯ There were more local reactions in the AgB/RC-210-04 group, however they were transient and this double-adjuvanted formulation was well tolerated. We conclude that the addition of a synthetic adjuvant to the AgB vaccine significantly enhanced the immunogenicity of the commercial vaccine AgB. The results indicate furthermore that a two-dose regime of the double-adjuvanted vaccine (schedule: 0-1 month) may be sufficient to achieve seroprotection in nearly 100% of individuals.
